APPARATUS AND METHOD FOR DOPPLER-ASSISTED MIMO RADAR MICROWAVE IMAGING

摘要

A method and apparatus for enhanced microwave imaging of an object collects (200) microwave responses for multiple combinations of transmit antennas, receive antennas, and object movement states. The responses are grouped (204) into sets of responses corresponding to at least two object movement states. An image is reconstructed (206) from the set of responses for each movement state, and a differential image representative of object movement is generated (208) from the reconstructed image for each of said at least two object movement states. The differential image is overlaid (210) on a reconstructed image to obtain an enhanced composite image of the object..
