Ground Moving Target Displacement Compensation for DPCA based SAR-GMTI System
The velocity and acceleration of the ground moving target can cause the target position to be displaced and defocused in the SAR image.In this paper,the displacement compensation scheme is presented to correct the displaced position and defocused moving target image in the DPCA based SAR-GMTI system. The influence of the ground moving target due to the velocity and acceleration is analyzed in range and azimuth directions,and its compensation method is presented with the simulation results. The performance of the proposed method is compared with respect to the estimated velocity and defocused quantity in both range and azimuth directions.
