Spaceborne SAR Real-Time Qucik-Look System

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