摘要
This paper presents a new scheme for moving target velocity estimation in conventional high-resolution wide-swath (HRWS) SAR systems. A generalized steering vector is designed for azimuth ambiguity suppression and the velocity parameter of the moving target is involved in this modified steering vector. The low PRF in HRWS-SAR systems will result in serious azimuth ambiguity. When the adopted parameter is matched with the real velocity of the moving target, its azimuth ambiguities will be suppressed clearly. Entropy can be used to measure the performance for azimuth ambiguity suppression. The velocity can be estimated through searching the matched velocity. Finally, the effectiveness of the proposed approach is verified by simulated multichannel SAR data.
