Abstract: 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.
