The Research and Implementation of Spaceborne SAR Real-Time Quick Look Imaging System

Many kinds of quick look imaging algorithms of spaceborne SAR are compared. And according to certain parameters of a spaceborne SAR system, optimized real-time imaging algorithm is proposed.Based on DSP parallel processing technology, the design and implementation of a real-time quick look system is presented. The system is used to fulfill 1/4 resolution of range and four-look of azimuth real-time imaging of L band spaceborne SAR Data. Finally, the results of image quality measures are available.
