Abstract
When airborne/missile borne radar works in forward-looking State, it is difficult to obtain high angle resolution because of the small doppler difference of targets at different angles in the imaging scene. Aiming at the forward looking imaging application of ship targets at sea, a forward looking imaging angle resolution en-hancement method is presented based on compressive sensing with complex approximated message passing (CAMP) algorithm. The linear Observation signal model of forward-looking imaging is established. The iterative calculation process of CAMP and the processing flow of multi-channel radar forward-looking imaging are presented. The validity of the method is verified by Simulation data and processing results of X band radar meas-ured data.
