The Nonlinear Chirp Scaling Algorithm for Bistatic SAR Imaging
双站SAR NCS成像算法

To the big squint mode of bistatic SAR system,based on the echo model of bistatic SAR and range equation in RD area,properly to with the NCS algorithm of conventional SAR,this paper proposes NCS algorithm for squint-looking bistatic SAR,and carefully analysis two key problems in this algorithm:azimuth ambiguity of Doppler center and imaging position in range direction.Finally,it is proved to be valid by the simulation results.
