| Abstract: | This paper derives the dechirp formula of bistatic SAIL The echo signal model is presented. The imaging formation and computation effective of back projection are analyzed. The main steps are also given. When the bistatic angle is 90, the simulation experiments are conducted. With the quantitive analysis of point spread function, the back projection algorithm for bistatic spotlight SAR is validated. |
