基于光电对偶的微波视频成像技术

Microwave Video Imaging Technology Based on Optoelectronic Collaborative Method

为解决在严苛环境条件下高分辨率微波遥感的实时成像难题,区别于以DSP为主要处理器的方案,设计了一种基于光电对偶的微波视频成像系统。将合成孔径雷达(SAR)信号调制在激光束上,以光学形式完成主体运算,并通过CCD获取成像结果。该系统具有功耗低、运算延迟小的特点,并兼容现在通用的SAR数字信号处理算法,实现了一个计算以光为主、控制辅助以电为主的处理系统。

In order to solve the real-time imaging problem of high-resolution microwave remote sensing under harsh environmental conditions,a microwave video imaging system based on optoelectronic collaborative technology was designed,which was different from the scheme using DSP as the main processor.The signal of synthetic aperture radar(SAR)was modulated on a laser beam,and the main operation was completed in optical form.The imaging results were obtained through CCD.This system has the characteristics of low power consumption and low operational delay,and is compatible with the common SAR digital signal processing algorithms.A processing system has been realized which primarily relies on light for computation and electricity for control assistance.
