Abstract :
This paper presents an imaging method of FMCW SAR with diving acceleration. The motion parameters measured by the GPS/IMU integrated navigation device on the platform are used for constructing the target range expression in high-order approximation. The series reversion algorithm is used to evaluate the accurate expression of the received signal in Doppler frequency domain. The simulation is presented to show the effectiveness of the proposed method.
