摘要

本文研究ISAR雷达目标回波的信号检测方法.由于ISAR雷达目标检测实质上是延伸目标检测(Extended target detection)

其目标散射模型不是低分辨雷达(LRR)中的等效点目标.在距离维上呈现出多个强散射点

.本文提出的目标回波的检测方法是对同一目标的距离维上各散射点进行相关积累

以提高雷达目标信噪比.分析和实际结果表明:利用本文所提出的雷达目标检测方法比低距离分辨(LRR)雷达的性能有很大的改进.

Abstract

This paper deals with feature of extraction target signal with ISAR radar.Since the size of the rarget is larger than range resolution of ISAR radar

the back-scattered power of the target is represented as a function of time.The method of improved detection performance with ISAR are FFT and signal amplitude integration of each range cell

which presents the signal of the target.But in LRR the signal integration is vectoried integration

the output forms of the methods are given by this paper and theoretical calculation agrees with experimental measurement satisfactorily.
