Patent ID: 8791851

Claim:
An imaging system, comprising: sensors of a first type and sensors of a second type on a single plane; a first array of printed antennas located on a first side of a printed circuit board (PCB) and electrically coupled to first receive circuits located on a second side of said PCB through vias, the first receive circuits connected to the sensors of the first type; a second array of printed antennas located on said first side of said PCB and electrically coupled to second receive circuits located on said second side of said PCB through vias, the second receive circuits connected to the sensors of the second type; at least one transmitter; and a detection and decision block, wherein the imaging system is adapted to acquire a first image in a passive scan in radiometric mode, and in response to positive detection results, to illuminate an imaged object with coherent radiation, and acquire a second image in an active scan performed in reflectometric mode, wherein the sensors of the first type and the sensors of the second type are active in acquiring the first image, and the at least one transmitter, the sensors of the first type and the sensors of the second type are active in acquiring the second image, and wherein the detection and decision block is adapted for control and data information exchange.
