The system and method for standoff detection of human carried explosives (HCE) automatically detects HCE 112 up to a range of 200 meters and within seconds alerts an operator to HCE 112 threats. The system 100 has radar only, or both radar and video sensors, a multi-sensor processor 102, an operator console 120, handheld displays 122, and a wideband wireless communications link. The processor 102 receives radar and video feeds and automatically tracks and detects all humans 110 in the field of view. Track data continuously cues the narrow beam radar 118 to a subject of interest 110, 112 the radar 106, 108 repeatedly interrogating cued objects 110, 112, producing a multi-polarity radar range profile for each interrogation event. Range profiles and associated features are automatically fused over time until sufficient evidence is accrued to support a threat/non-threat declaration hypothesis. Once a determination is made, the system 100 alerts operators through a handheld display 122 and mitigates the threat if desired. |
