| Abstract: | On the basis of the conventional algorithm, the echo model ofbistatic SAR and the range equation in RD area were given, the bistatic SAR based ECS algorithm was presented, the three types of compensation factors for the algorithm were derived, and then the imaging position in the direction of range was also analysed. Finally, the feasibility of the algorithm is validated by simulation results. |
