Abstract

CS (Chirp Scaling) Algorithm is practical in the SAR realtime imaging and attracts attention from researchers all over the world.The imaging-quality of CS Algorithm depends on the generating methods of three phase factor (Chirp Scaling factor,range compensation factor,azimuth compensation factor).This paper introduces a kind of method of utilizing CS Algorithm for real-time processing of the on-board SAR image and the realization on the DSP processor TS101S,the author provides the programming optimization of assembly language ,which improves the efficiency of an average of 10%.
