Abstract：The wide-swath method based on multi-receiver is a novel and highly accuracy wide-swath method. This method needs focus in range signal at first, so RD (Range-Doppler) arithmetic can apply to the method easily while CS (Chirp Scaling) arithmetic has some difficulties. An algorithm based on CS algorithm is proposed in this paper that can be applied in the multi-aperture wide-swath SAR method. The error and operand of this algorithm is analyzed. Finally the simulation result is present, it turn out to validate the algorithm.
