Abstract :
This paper analyzed the imaging processing gains of the CS imaging algorithm (CS) and the RD imaging algorithm (RD) on both the signal and the oppressive jamming. According to above analysis, the conclusion is drawn that the anti-jamming capability of RD is better than that of CS. However, CS fits the spaceborne SAR imaging with large range cell migration well. The echo data are processed through the pre-filter to improve the anti-jamming capability of CS. The anti-jamming capability of RD is identical with that of the pre-filter processing CS algorithm (pre-filter processing CS). Finally, the simulated data and the real data are processed respectively. The simulation result verified the validity of the analysis.
