Abstract :
This paper puts forward a quick-look algorithm for reduced resolution SAR imaging processing, an analysis of the algorithm principle, the FIR filter choice, a correction method for the filter phase and altitude errors, addition modes on the azimuth direction, and the correction of the distance movement error and azimuth spectrum center. Experiments with satellite-borne SAR raw-data show that this algorithm needs a very small calculation time and a small memory volume to get good quality reduced-resolution SAR images
