实时光电混合SA■数据处理器

Real-time Optical/Electronical Hybrid SAR Data Processor

设计了一种光电混合综合孔径雷达(SAR)数据处理器,它利用声光器件(AOD)作为实时输入电-光转换器,利用光学系统实现SAR数据距离维的聚焦,利用CCD完成SAR数据在方位维的压缩并同时输出处理后的SAR图像。给出了实验室实时完成SAR数据距离维聚焦的有关图片。

A real-time optical/electronical hybrid synthetical aperture radar(SAR)data processor has been designed, which uses AOD as real—time input electronic-to-optical transducer, utilizes optical system to realize range dimen sion focussing of SAR data and uses CCD to perform azimuth compression of SAR data. Simultaneously CCD outputs the processed SAR images. Finally, the related photographs of range focusing taken in the experiment are given。
