星载合成孔径雷达(SAR)数据的光电实时处理技术

Real-time Optoelectronic Processing Technology for Spaceborne Synthetic Aperture Radar(SAR)Data

由于在光源、空间光调制器(SLM)和探测器等方面的新进展,使得实时光信号处理器的实现成为可能;这种处理器具有成本低、能耗小、结构紧凑等优点。本文中描述了一个 SAR 实时光电处理器,并着重强调了 SAR 成像和处理器的基本原理,最后对处理器中的一些问题进行了讨论。

Recent advances in light sources,spatial light modulators (SLM)and detectors have made it possible to implement real- time optical signal processors that are relatively compact with low power reqirements and cost.In this paper a reai-tlme optoelec- ironic processor for SAR is described with the emphasis on the fundamental principle of the imaging and the processor,followed by some problems in the processor.
