This paper is about the processing of the burst mode Space borne ScanSAR data There are many algorithms developed for processing the strip mode space borne SAR data

for example;the RD algorithm

the Specan algorithm

the Chirp Scaling algorithm

the Ω k algorithm However

due to the bursting characteristics of the ScanSAR data and the operation mode of the ScanSAR

none of the above algorithms can be used directly in the processing of the Space borne ScanSAR data In this paper

the time domain and the frequency domain characteristics of the ScanSAR echo were analyzed Based on the understanding of RadarSAT ScanSAR data and the characteristics of the ScanSAR echo

the full swath RD algorithm

fast SPECAN algorithm and Chirp Scaling algorithm were developed The RD algorithm for whole scanned swath is an effective algorithm

the SPECAN algorithm can provide a high resolution image quickly and the chirp scaling algorithm has an excellent phase preserving ability In the real data processing

some methods like the side lobe control of point target echo

the fast range walk correction

the scalloping weakening

the range ambiguity control

the azimuth false target elimination and the Doppler centroid frequency estimation were discussed and verified
