Abstract

Abstract

Base on the analysis of SAR linear FM waveform and Doppler history, a modified spaceborne SAR quicklook algorithm is proposed, the algorithm s mathematical model is also constructed. Then a method of how to mosaic the sub-image together is given by analyzing Doppler history. Finally, by processing ERS-1 raw data, the results indicates that the quicklook algorithm is precise and efficient.
