Abstract An advanced algorithm is proposed to obtain forward-target image on a curve trajectory, which causes a serious range coupling. The algorithm decreases efficiently the coupling with Range Walk Correction (RCM) in time domain firstly. The 2-dimision frequency domain expression is presented with series reversion. The correlative coefficient of ECS algorithm is obtained, and SAR image is got with ECS. Finally simulations show the validity of the proposed algorithm.
