Abstract :
This paper firstly describes the processing of Range-Doppler imaging algorithm and FFT interpolation for range cell migration correction, and then forms a improved range-doppler algorithm for SAR imaging with combining the two methods, which has much less computation time. In order to eliminate computation further, the Pruning FFT technique is used.
