A MODIFIED SPACEBORNE SAR QUICKLOOK ALGORITHM

该文针对合成孔径雷达(SAR)发射线性调频波形和多普勒历程的特点,提出了一种改进的星载SAR快视处理算法。首先建立了算法的数学模型,给出了SAR快视图像精确拼接的方法,最后通过对ERS-1条带数据的快视处理,验证了该快视算法的有效性和高效性。

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.
