Abstract
Systems and methods are provided for recognizing a human being behind a barrier using a radar image. A millimeter band radar assembly captures radar returns from a region of interest, at least a portion of which is separated from the millimeter band radar assembly by the barrier. A system control processes the radar returns to provide at least one radar image showing the amplitude of the radar return in each of a plurality of locations within the region of interest. The system control includes a sensitivity tuning component that adjusts a noise floor for the processed sensor data to provide an image of the at least one radar image tuned to maximize the visibility of the human being. A display provides the radar image to a user.
