Multiple-working-mode real-time SAR quick vision system

The invention provides a multiple-working-mode real-time SAR quick vision system which comprises an original data recording and distributing subsystem, a real-time decompression and imaging subsystem,a comprehensive displaying and analyzing subsystem. According to the multiple-working-mode real-time SAR quick vision system, serial Rapid IO is used for communication, and furthermore a mode of parallel processing of a plurality of DSPs is utilized for performing imaging processing in an SAR strip mode, a scanning imaging mode, an ultrafine mode or a sliding beam focusing mode, thereby obtainingan SAR load image data frame, and quickly displaying the SAR load image data frame. The multiple-working-mode real-time SAR quick vision system realizes real-time quick vision processing to multiple-working-mode SAR echo data. 本发明提供了种多工作模式的实时SAR快视系统，包括原始数据记录与分发子系统、实时解压缩及成像子系统、综合显示与分析子系统，该系统采用串行Rapid IO进行通信，同时采用多个DSP并行处理的方式对雷达回波数据进行SAR条带模式、扫描成像模式、超精细模式或者滑动聚束模式的成像处理，得到SAR载荷图像数据帧，并将SAR载荷图像数据帧快速显示。该系统实现了多工作模式SAR回波数据的实时快视处理。
