合成孔径雷达(sar)数据处理是从最早的光学处理模式转变到现在的数字信

Synthetic aperture radar (sar) data processing is shifted from the earliest optical processing mode to the current digital signal processor (dsp) processing mode. However, with the improvement of the resolution of the synthetic aperture radar and the increasing demand for real-time imaging in orbit, the traditional digital processing methods are being challenged. Because of the limitation of the space environment and the power consumption of the system, the requirements for real-time imaging in orbit can no longer be met. So there is an urgent need to find a new solution. Therefore, optical processing methods with low power consumption, simple equipment, fast optical operation speed, and strong parallel processing capability are adopted again. <br>In order to solve the problem of on-orbit imaging processing of spaceborne synthetic aperture radar, a new type of photoelectric cooperative processing system was designed, namely the spaceborne synthetic aperture radar data photoelectric cooperative processing system, which integrated SAR data processing into the optical system.
