摘要： Methods and systems for object localization include identifying associations between measurements taken from radar sensors. A shared coordinate system for the radar sensors is determined based the identified associations, including identifying translations and rotations between local coordinate systems of the radar sensors. A position of an object in the shared coordinate systems is determined, based on measurements of the object by the radar sensors. An action is performed responsive to the determined position of the object.

摘要： Radar signal processing is performed using a plurality of signal processing units onboard a radar sensor unit. One of the signal processing units is designated as the primary processor whereas the remaining signal processing units are designated as secondary processors. Secondary processors, based on their configuration and capability, perform a subset of radar signal processing tasks. Secondary processors transmit a compressed bit stream of their partially processed results to the primary processor. The primary processor decompresses the bit streams received from a plurality of secondary processors, incorporates the partially processed results from a plurality of secondary processors with its locally processed results, performs final detections, and sends the final detections to a remote processor. When secondary processors perform detections in range, Doppler, and angle domains, and sends those to the primary processor, the primary processor employs consensus detection to produce final detections.

摘要： An electronically steerable phased array and switching network connected to an FMCW radar transceiver to enable a low-cost monopulse tracking system that covers a wide field of regard using electronic beam steering. In a first mode, beamformer integrated circuits (BFICs) at each element in the array are switched synchronously with transmit/receive (T/R) switches located at the subarray level. This allows the entire aperture to be switched between transmission and reception, enabling the FMCW radar transceiver to be operated in a pulsed configuration. In a second mode, a portion of the T/R switches at the subarray level and all of the connecting BFICs at the element level are fixed in either transmitting or receiving mode, allowing separate portions of the aperture to concurrently transmit or receive. The arrangement of transmitting and receiving subarrays can be dynamically reconfigured to allow for accurate bearing and azimuth estimation using alternating monopulse.

摘要： An each pattern is provided a reception pathway, the method uses the synchronous replies and the asynchronous replies, unsolicited of Fruit type, transmitted by targets present in the aerial environment of the radar and detected over a given number of antenna revolutions. At each detection of a reply the value of its off-aim in bearing and the value of relative power received on each of the pathways are calculated as is its elevation by extrapolation with the synchronous detections close to the same target and associated with the detection. The values obtained over the given number of revolutions are stored, the measured patterns being sampled on the basis of the stored values.

摘要： A system for using wireless signals to detect objects of a certain type, such as concealed weapons, leverages the fact that different objects have different resonance characteristics. The system transmits wireless signals of different frequencies, and returns from such signals are measured. The return of a signal from an object at a resonant frequency of the object will be stronger than a return of a signal from the object at a non-resonant frequency. The system analyzes the returns in an effort to determine when a return is sufficiently large to indicate that it was reflected from an object of interest. When an object of interest is detected, the system adjusts a characteristic of the system, such as antenna orientation or pulse shape, based on an estimated location of the object, and then runs a test to confirm the detection of the object, thereby eliminating at least some false positives.
