摘要： A non-wearable Personal Emergency Response System (PERS) architecture is provided, implementing RF interferometry using synthetic aperture antenna arrays to derive ultra-wideband echo signals which are analyzed and then processed by a two-stage human state classifier and abnormal states pattern recognition. Systems and methods transmit ultra-wide band radio frequency signals at, and receive echo signals from, the environment, process the received echo signals to yield a range-bin-based slow signal that is spatially characterized over a plurality of spatial range bins, and estimate respiration parameter(s) of the human(s) by analyzing the slow signal. The antennas may be arranged in several linear baselines, implement virtual displacements, and may be set into multiple communicating sub-arrays. A classifier uses respiration and other derived features to classify the state of the human(s). A decision process is carried out based on the instantaneous human state (local decision) followed by abnormal states patterns recognition (global decision).

摘要： In a general aspect, a filter time aligns time varying RF-motion data. In some aspects, a method includes loading a first set of input signals (SISs) into an interference buffer over a first time period. The first SISs is based on a first set of wireless signals received by a wireless communication device (WCD) after being transmitted through a space. The method includes using the first SISs to determine an interference level. The method includes: in response to determining the interference level is below a threshold, executing a motion detection process in a second, subsequent time period over which a second SISs is loaded into the interference buffer. The motion detection process, using a subset of the first SISs, detects motion of an object in the space. The second SISs are based on a second set of wireless signals received by the WCD after being transmitted through the space.

摘要： A motion detector and a method for operating the motion detector including a radio frequency (RF) transmission circuit, an RF reception circuit, and a controller that is electrically coupled to the RF transmission circuit and the RF reception circuit. The controller is configured to control the RF transmission circuit to generate an RF signal and control the RF reception circuit to receive a reflected RF signal from a target object in a predetermined time for reception after transmission of the RF signal. The controller is further configured to control the RF reception circuit to generate a Doppler signal indicative of a distance between the target object and the motion detection system based on the reflected RF signal. The controller is further configured to adjust a sensitivity of the RF reception circuit during the predetermined time for reception and activate an indicator based on the magnitude of the Doppler signal.

摘要： A method and apparatuses may be provided for detection, tracking, and classification of one or more land, maritime, or airborne objects using a real-aperture radar mounted on a parasail airborne platform. Both wide-area and localized radar surveillance can be provided, and the radar can be either a non-coherent radar or coherent radar. A method and apparatus may use a low-cost, rotating, single-beam, non-coherent, X-band radar that is mounted on an unmanned powered parasail and operated remotely like an Unattended Airborne System (UAS). The parasail, which may be expendable or recoverable, manned or unmanned, powered or unpowered, may have a low operational cost, can carry a heavy payload, stay on station for a long time, circle or move to a specified location for surveillance, operate at an optimal altitude and look-angle, and automatically cue or manually steer an EO/IR camera to a target of interest for classification and identification.

摘要： A system and method for object detection in a wireless network. A wireless communications device receives a first set of wireless signals on a first frequency band, and generates a first interference profile for the wireless network based on signal interference in the first set of wireless signals. The wireless communications device further receives a second set of wireless signals on a second frequency band, and generates a second interference profile for the wireless network based on signal interference in the second set of wireless signals. The wireless communications device then detects the presence of an object in the wireless network based at least in part on the first interference profile and the second interference profile.

摘要： System and methods for surveying areas using a radar system and an unmanned aerial vehicle (UAV) are described herein. For example, one or more embodiments include detecting an event in the area using movement measurements from a radar system, wherein the radar system transmits electromagnetic radiation waves to capture the movement measurements in the area, and determining geographic information system (GIS) coordinates of a location of the event. Further, one or more embodiments can include navigating an UAV to the location substantially autonomously using the GIS coordinates of the location of the event and capturing a second number of images of the location using the UAV.

摘要： An undercarriage vehicle inspection system (UVIS) disposed below a rail bed or road way uses an array of dual mode sensors comprised of short range, high resolution radar sensors disposed with high resolution electro-optical sensors, sharing identical field-of-regard, positioned to illuminate a small sector of the vehicle underside, to collect sensor signatures over the small sector, fuse the signatures from the radar and electro-optical sensors, create a three-dimensional map record of the undercarriage when the vehicle passes overhead. The dual mode sensor array processor collects signatures across the width of the vehicle undercarriage to create a strip map record. As the vehicle passes overhead the dual mode UVIS, repeats that signature collection method until strip maps are created and stored representing the entire vehicle undercarriage. The undercarriage array map consists of three- dimensional cells having metrics for length (L) across the undercarriage, width (W) in direction of vehicle undercarriage. The dual mode array map cell signatures collectively represent the entire underside contour data file that is collected and recorded for future comparison. In subsequent passage of the subject vehicle over the dual mode sensor array a new three-dimensional data record is generated by the system processor and subjected to comparison with earlier recorded three-dimensional data record for the vehicle to search for change in the three-dimensional data record. Change in the data record for one or more cells across one or more strips over the length of the vehicle will cause the processor to activate an alert device for a human operator for purpose of subsequent inspection by the human operator whether the change is indication of terrorist threat or need for maintenance of the underside equipment.
