摘要： An ultra-wideband (UWB) system includes an enclosure, and an ultra-wideband (UWB) transmitter array within the enclosure, the UWB transmitter array having a transmitter component that transmits electromagnetic waves toward a region-of-interest (ROI), the UWB array having a receiver component that receives reflected electromagnetic waves from objects in the ROI and generates object data. The system further includes a radar absorbing material positioned to receive electromagnetic waves transmitted from the transmitter component that are not directed toward the ROI, and a pattern recognition device having a processor configured to process the electromagnetic waves reflected from the ROI and to determine whether an object-of-interest (OOI) pattern is recognized within the object data.

摘要： A system includes an ultra-wideband (UWB) array having a transmitter that transmits electromagnetic waves as UWB pulses toward a region-of-interest (ROI), and having a receiver that receives reflected electromagnetic waves from objects in the ROI and generates object data, and a pattern recognition device having a processor configured to provide operations. The processor is configured to provide instructions that obtain scanning data from reflected electromagnetic waves from the ROI until an event is triggered, when the event is triggered, access a heuristic created from calibration data that was previously obtained using the ROI and using the UWB array, analyze the scanning data with the heuristic utilizing a pattern recognition function derived from the calibration data, to determine whether an object-of-interest (OOI) pattern is recognized within the scanning data, and if an OOI pattern is recognized, generate an alert.

摘要： A system includes an ultra-wideband (UWB) radar having a transmitter that transmits electromagnetic waves toward a region-of-interest (ROI) and a receiver that receives reflected electromagnetic waves coming from the ROI. The system also includes at least one device configured to detect metal in a lower region of the ROI, a pattern recognition device, and a signaling device. The pattern recognition device includes a processor and is configured to identify at least one object-of-interest (OOI), via the reflected electromagnetic waves, that is moving through the ROI. The signaling device is configured to send an alert when i) the pattern recognition device identifies an OOI and ii) metal is detected by at least one metal detector or the at least one magnetometer.
