超高速DSP在机载SAR成像处理中的应用

Application of Ultra-High Speed DSP for Airborne SAR Imaging Processing

本文首先简单介绍了合成孔径雷达（ＳＡＲ）成像原理，并对以超高速数字信号处理器（ＤＳ）为核心的机载合成孔径雷达实时成像处理系统的硬件结构作了描述。从理论上分析了该系统的主要性能指标并给出了该系统的实测结果，最后给出了机载合成孔径雷达原始数据的成像结果。

This paper presents the principle of Sythetic Aperture Radar(SAR) imaging and describes the system hardware of airborneSAR real-time digital signal processing system with ultra-high speed DSP .Then the main technical parameters are analyzed briefly,and finallythe experiment results of the system and examples of imagery horn raw data obtained by the system are also presented.
