Abstract: A threat detection system having a reconfigurable reflect-array and compressive sensing unit to effectively detect objects that are a threat is presented. A statistical library, having a wide range of threat and non-threat examples and capable of incorporating new examples while being used, is utilized by several optimization algorithms to calculate an optimal illumination pattern for compressive sensing detection. The reflect-array is configured to produce the optimal illumination pattern via a plurality of reflect-array elements. In this way, a plurality of data may be parallel processed, thereby increasing the detection speed and reducing cost.
