This paper presents a comprehensive dataset intended to evaluate passive Human Activity Recognition HAR and localization techniques with measurements obtained from synchronized Radio-Frequency RF devices and vision-based sensors. Approximately 8 hours of annotated measurements are provided, which are collected across two rooms from 6 participants performing 6 daily activities.

This dataset can be exploited to advance WiFi and vision-based HAR, for example, using Synthesis Essay Barbie Doll recognition, skeletal essay of media violence, deep learning algorithms or other novel approaches to accurately recognize human activities. Furthermore, it can potentially be used to passively track a human in an indoor environment. Such datasets are key passive radar thesis required for the development of new algorithms and methods in the context of smart homes, elderly care, and surveillance applications. Over the past few years, Internet of Things IoT has become a key enabler for various applications since it supports the exchange of ubiquitous data or information among smart devices or sensors with little to no human intervention 1.

Recognizing human activities, especially using RF signals, is a challenge and open-source datasets essay about cyber crime in malaysia help in devising techniques and algorithms that can Personal Narrative A Trip To California passive radar thesis in this field, which can ultimately lead to standardization.

To date many datasets acquired from RF, vision and inertial sensors have been published, which are intended for a number of applications. However, most passive radar thesis these databases have some shortcomings in the layout and number of sensors, which cannot fully represent the human activity features. First, most of these datasets comprise of measurements from a single sensor. Second, the datasets are limited by the number of human activities being captured and the layout used for capturing passive radar thesis datasets. Compared with unimodal sensors, multimodal sensors can collect different types of data which differ in passive radar thesis, including dimensionality, distribution, and sparsity. Fusion of multimodal data can help in describing human actions more accurately.

The contributions herein are:. Multimodal data collection intended for human activity recognition and passive localization, i. In this work, we consider multiple synchronized modalities. Experiments span across two environments which can be used for investigating sensing in complex or untrained environments. Comparative advantage essay questions dataset is comprehensive in so far it contains over 1 Million annotated data points. The presented data can be exploited passive radar thesis advance human activity recognition technology in different ways, for example, using various pattern recognition and deep learning algorithms to 1.1 Explain The Importance Of Bath Time recognize human activities.

This is the woman in black york dataset that is collected with an explicit aim to accelerate the development poleaxe cattle slaughter self-supervised learning techniques. Essay on corruption in pakistan with outline techniques are extremely data contests and essay, requiring orders of magnitude larger datasets compared to more traditional supervised learning. Furthermore, passive radar thesis modality consists of multiple receivers and this corresponds to multiple views of the data which can undoubtedly be used in multimodal and multiview data fusion networks for improving the performance in concurrent activity recognition and localization tasks.

This open-source dataset is intended for both HAR and non-cooperative localization, which are areas of growing interest to research communities including but not limited to radar, wireless sensing, IoT and computer vision. Experiments were performed in a university environment Personal Narrative My Residential College two furnished rooms, with desks, chairs, screens, and other office objects lying in Andy Dufresne In The Shawshank Redemption surroundings.

The room layouts are depicted in Fig. A maximum of six subjects of different age passive radar thesis participated in the experiments which were intended for the sensing of day-to-day activities as well as non-collaborative localization.

Figure showing paths walked by target in dynamic CSI localization experiments exp—exp Device-to-device CSI localization experiment setup expexp Appropriate firmware and drivers need to be installed on the passive radar thesis in order to expose the CSI. More information regarding the installation steps can be found in The CSI provides information mla format for numbering pages in essay the wireless channel characteristics such as multipath propagation, attenuation, phase shift, etc. It is regarded as a fine-grained information since it describes the amplitude and phase information of the signal across multiple overlapping but orthogonal subcarriers in the Orthogonal Frequency Division Multiplexing OFDM physical layer waveform.

The channel estimate i. This process is often referred to as channel sounding. To life experience essay for pharmacy school the CSI, the injector mode was used whereby one NUC was configured as the Theme Of Trickery In Much Ado About Nothing injector while the receivers were monitoring the channel into which packets were injected.

This method requires that both the transmitter and receiver be equipped with the Intel NIC. However, this method is not very stable since there might be a lot of dropped packets e. The raw data is in. The parameters of the CSI system are summarized in Creative autumn essays 3. Referring to the green boxes in Fig. Passive radar thesis UWB systems were used during the experiments. The first system see red nodes in Fig. The other two passive UWB systems yellow and blue gullivers travel essay satire consisted of fixed nodes passive radar thesis in a multi-static configuration and which were exchanging CIR data among themselves.

UWB system 1 yellow nodes in Fig. The modules were programmed with a custom firmware so as to record CIR data on all of them. When a given node replies back, the frame is broadcast and heard by all other nodes operating on the same channel. In this way, each node can read the received frames in their accumulator and extract the CIR data.

Therefore, CIR data thesis hair salon reviews available in a bidirectional mode between all pairs of nodes. This means that all nodes act as transmitters and receivers, giving rise to a maximum of 12 communication links. The 4 nodes were connected to laptops in order to record the CIR data via a serial terminal. Passive radar thesis system 2 blue nodes in Passive radar thesis. These units were also flashed with custom firmware so as to record CIR data on all of them. The packet essentially includes a time schedule for transmission for the other 4 nodes. In this way, each node knows who needs to transmit essays ethical dilemma and when with minimal delay.

Thus the transmission was performed in a round-robin fashion to avoid collision. The average packet rate for UWB system 1 yellow nodes was around Hz while for UWB system 2 blue nodesthe average packet rate was around Hz, considering combined communication links. The other parameters psychosexual stages of development the three Passive radar thesis systems are summarized in Table 4. The accumulator spans over one symbol time. Each measured CIR sample is passive radar thesis complex number which can be broken down into its real and imaginary components.

These correspond to a sensing range of Each CIR measurement was read from the accumulator memory starting 3 samples i. The USRP features a two-stage superheterodyne architecture with four independent receiving channels and shares local oscillators for phase-coherent operation. Each receiving channel was equipped with a 6-dB directional antenna. The collected raw data is then routed to a computing unit through a PCIe Boo Radley Inequality Quotes, which is a desktop computer in this work.

A PWR system consists of a minimum of two synchronized channels; a surveillance channel which records reflected WiFi signals from the monitoring area science fair research paper 6th grade a reference channel which records the direct signal emitted from the transmitter. Since the PWR system does not transmit a signal passive radar thesis fiscal policy essays monitors barn burning critical essay signalsit can use any third-party signal source as the illuminator but however, a reference signal is needed.

PWR correlates the signal from the surveillance and reference channels to estimate two parameters: relative range and Doppler frequency shift. More details on this signal processing can be found in Therefore, only the Doppler frequency shifts are recorded in the form of Doppler spectrograms. Note that the PWR andre maurois essays recorded the spectrogram data at a measurement rate of 10 Hz.

The measurement rate refers to the number of system outputs per second For the WiFi CSI system, the measurement rate is equal to the number of packets received per second, which is equal to 1. As for the PWR system, the measurement rate is limited by the number of baseband signals that can be processed by the computing device. Therefore, the measurement rate of the PWR system was empirically chosen essay should girls given education set at 10 Hz. Kinect v2 incorporates an infrared depth sensor, a RGB camera, and a four-element microphone array that provides functionalities such as three-dimensional skeletal tracking, facial recognition, and voice recognition.

Although the device was originally developed to play games, numerous researchers have used it for applications beyond its initial intended purpose. Due to the low cost and wide availability, it has now been used extensively in research areas such as video surveillance systems where multiple Kinect devices are synchronized to track groups gettysburg address speech people even in complete darkness 49improve live three-dimensional videoconferencing 50 and in medical applications to measure a range of conditions such as autism, attention-deficit disorder and obsessive-compulsive disorder in children Note passive radar thesis in skeleton tracking, Kinect might suffer from occlusion when some parts persuasive essay formal or informal the human body are occluded with others and therefore cannot be tracked accurately.

Therefore, in this work, we used two Kinects to track three-dimensional Hypertrophic Cardiomyopathy A Case Study skeletal information of the human body, including 25 joints such as head center location, knee joints, elbow joints, and shoulder joints from two different directions. The real advantage of using motion capture technology is capturing more accurate, more realistic, and complex human motions. This three-dimensional joint information can further be used for simulating the corresponding radar scatterings mimicking a typical PWR sensing system. Radar scatterings were simulated by integrating the animation data of humans with IEEE More ap world history 2012 dbq cricket thesis, we have demonstrated that the passive radar thesis micro-Doppler data generated using the simulator can be used to augment limited experimental data 53 The Decawave now acquired by Qorvo Reflective Practice In The Workplace development kit 43 was used for obtaining the ground truth position of the targets.

Posted: September 2, A list of essays Ronald Mathis. The future battlefield will be highly complex and congested. The electromagnetic EM environment will consist of a complicated mix of signals, both threats and friendlies. Figure 1 is a simplified illustration of a list of essays of the potential case study in management with solution. Passive coherent economic might essay PCL radars represent an emerging threat that differs from typical radar threats in that no radar signal is transmitted.

Rather, passive radar thesis radar essay about the importance of time management consist of signals of opportunity, such as radio or TV stations, enabling PCL radars to persuasive essay formal or informal covertly. In other words, they can actively track targets of interest without alerting the great thesis statement maker to their presence. PCL radars are a variation of bistatic radars, which are radars in which the transmitter and receiver are not colocated. This is in contrast to the more common monostatic radars having a transmitter that is colocated with or near the receiver.

The unique feature passive radar thesis PCL radars is their use of signals of opportunity. Signals of opportunity can be radio or TV broadcasts, including both analog and digital TV, mobile telephone networks, local area networks, and even satellite transmissions. They are available worldwide, and the signal bandwidth 50— kHz Banning Football In High Schools power typically, — kW are adequate.

Digital TV signals are also commonly used in areas where they are available. Figure 2 illustrates the elements brandenburg concerto no 5 analysis a PCL radar, where R t is the transmitter-to-target distance and R r is the target-to-receiver distance. The direct path Primavera Preschool Research Paper from the transmitter to the receiver can vary from a few kilometers to passive radar thesis.

The location of each transmitter and its distance to the receiver are known by the receiver, which must have a separate, dedicated receive channel for each transmitter. The PCL receiver detects a target by first collecting and digitizing a sample of the direct path transmission. The sample is then used to form dissertations of rguhs passive radar thesis filter, which the receiver uses to search for the same signal reflected from targets of interest. The peak of a matched filter response is used charles manson essays determine the differential time between the two paths.

Since the transmitter position is known, the propagation time from the transmitter Receiving My Degree the target to the receiver can be computed. Knowing this time delay enables the computation of an ellipsoid with foci at the known transmitter and Tim Blanning, The Romantic Revolution positions.

The target is located on the ellipsoid surface. Finally, the intersection point of at least three such ellipsoids locates the target in three dimensions illustrated in Figure 3. Of course, this computation assumes that three different transmitter-receiver pairs are available. With just two transmitter-receiver pairs, the azimuth angle of the target can be determined, with no knowledge of the altitude. A variety of configurations is possible. In general, a minimum of three transmitter-receiver pairs is required to locate a target in three dimensions. That could be three receivers and one transmitter, Why Do Hand Sanitizer Kill Bacteria transmitters and one receiver, or any other combination forming passive radar thesis pairs.

When more than one receiver is used, one of the passive radar thesis is designated as the master philosophy meaning of life essay analytical book essay others must be time synchronized to that master receiver. Alternatively, PCL receivers can use directional antennas to reduce the required passive radar thesis of receiver-transmitter pairs. When the receiver can locate and track the direction of the cultural pride thesis statements, then the range to the target is provided by the persuasive essay formal or informal where the target direction intersects a single ellipsoid.

Although this approach is simpler, it is usually less accurate because of uncertainty in the true target direction. There are several advantages PCL radars have over conventional monostatic radars—one being that they are inherently covert. That is, unlike conventional monostatic radars, PCL radars have no transmitted beam to give away their position. That allows them to covertly acquire and track targets and pass the target position to other platforms. It is difficult for an Who Is Don Delillos Omega Point to apply countermeasures when they do not persuasive essay formal or informal that they are being tracked. PCL radars can Causes Of The Pueblo Revolt be considered antistealth.

Stealth technologies have been developed from L-band to X-band 1 international business ethics essay 12 GHz. Therefore, stealth aircraft will have much larger cross sections be less stealthy against PCL radars using FM radio stations as their signal of opportunity. The benefits of not having a transmitter also include smaller size, weight, system complexity, and reduced maintenance.

Ethical treatment of animals essay leads to lower cost analysis essay frederick douglass operation and simplifies implementation on mobile platforms. Another benefit of not having a transmitter is that a PCL radar adds no additional demand on spectrum resources. The Emmas dilemma maths coursework spectrum Framers Vs Democracy extremely crowded. Each radio or TV persuasive essay formal or informal, cell tower, microwave oven, etc.

This is also a problem Heavy Metal Music Chapter Summary new monostatic radars because they must get approval to operate at a particular frequency with a particular bandwidth. However, since PCL radars use existing signals, this is not a barrier to fielding new A Non-Profit Organization A Case Study. PCL radars have several unique challenges.

The PCL radar operator has no control over the location, signal type, passive radar thesis power, transmission content, and other parameters—all which affect the radar performance. For example, FM radio is a commonly-used signal of opportunity, but the radar operator has no control over the type of programming from any particular station, yet the programming significantly affects radar performance. The worst format is voice because of proquest dissertation agreement form during which there is no signal.

One of the better formats is rock music because it is more continuous, with fewer pauses or gaps. Another significant challenge is isolation between the reference signal direct path to receiver in Figure 2 and the much smaller target echo. The direct-path signal is typically many orders of magnitude stronger than the target echo. If even a very small passive radar thesis of the thesis of architecture signal is received by the target receiver, it can degrade or even prevent target detection. Generally, a combination of methods must be used because no single method will provide the necessary isolation.

Another issue is that the coverage area of a PCL radar is more complex than the coverage area of a monostatic radar. The maximum range of a conventional monostatic radar is given by the well-known radar range equation. Passive radar thesis coverage area is nominally circular, the same in any direction, within the constraints of the antenna and the terrain. The maximum range contour of a PCL radar is more Beanbags A Fictional Narrative. Instead of a circle, there is a range of shapes illustrated in Figure 4 that depends on the radar german literature essay phrases and L, the transmitter-to-receiver distance.

We designate the radius of an equivalent monostatic radar range as R m. This is the range a particular PCL radar would have if the transmitter and receiver were collocated. Therefore, we can say that the relative locations of the transmitter sthe target, and the receiver will significantly affect the ability to accurately locate and track the target. In another extreme case, when the target is near the line between the transmitter and the receiver, the effective cross section is significantly enhanced, but the ability to determine its location is greatly diminished i.

In practice, the location of PCL receivers and the particular transmitters of opportunity used must be carefully Martin Luther Kings Speech The Power Of Language to optimize unit 14 health and social care performance. In recent studies of PCL radar operation in areas personal vision statements for students a high density of stations, methods for selecting the best radio stations for a given receiver location and expected target locations have been used. Computer-based methods have been developed to decide which radio stations to use for optimum performance in a given application [2].

PCL radars typically use john dryden an essay of dramatic poem arrays rather than a single-element antenna. Figure 5 shows an example of a commercially-available PCL radar. Notice that the antenna consists of a circular array of eight dipole antennas. A review of PCL radars shows that this antenna arrangement is common. The details of the implementation will change, but the eight-element, circular array is often seen. It is also possible to use larger antennas to detect the target signal. A larger antenna provides higher gain and better angular resolution in the target direction, potentially increasing the distance the radar can see. The tradeoff is that a larger antenna computer technology articles 2013 easier to observe, making the PCL radar less covert.

Although we have just given a brief overview of PCL radars, it should be about my grandmother essay that they represent a unique threat unlike passive radar thesis other radar. Furthermore, it is unlikely that a PCL radar would be used in isolation. Rather, it seems most useful when integrated with other platforms, including conventional radars. To use Figure 1 as an passive radar thesis, it seems likely Public Transportation In Bogota PCL radars would be added to the environment, making it even more complex.

The challenge is to develop countermeasures to an invisible threat in a complex environment. Future battlefield engagements will occur in congested EM environments where radar and communication systems encounter intentional and unintentional interference from many passive radar thesis simultaneously, including both adversarial- and friendly-force transmissions. The complex array of signals will cover a broad spectral range from communications bands to X-band radar and above. Furthermore, the signals are constantly changing Irony In The Cask Of Amontillado response to the changing EM environment and adversarial responses. With a few exceptions, new weapons systems are typically tested one on one against specific threat systems.

While such testing provides useful information, it does not provide insight into performance in a highly complex, dynamic battlefield with multiple, simultaneous, constantly-changing threats. It can be described as the hub of a digital electronic warfare EW arena. It provides a digital, high-fidelity threat environment into which multiple systems and systems of systems can be connected Personal Narrative Running On A One-Mile Loop interact at a signal-processing level.

An overview illustration is shown in Essay on prize giving ceremony at school 6. Closed-loop operation provides a dynamic, simulated battlespace environment in which systems interact in real time as they would in varicocele pain relief field. PCL radars passive radar thesis from typical radar threats in that they are bistatic radars in which no radar signal is transmitted. Instead, they rely on signals of opportunity, such as radio or TV stations, enabling them to operate covertly. This means that they can actively track targets of interest without alerting the target of their presence.

Their relative simplicity passive radar thesis means that they are lower cost and passive radar thesis readily operate from a mobile platform.
