摘要

在高频地波舰载超视距雷达中

雷达平台的运动导致了一阶海浪谱(Bragg谱线)的展宽.提取和检测落入此展宽区的目标是舰载条件下面临的主要困难.本文分析了Bragg谱线展宽的原因

提出了用单零点波束提取目标并用分裂的双零点波束测角的具体方法.在文章中用计算机对该种方法进行了仿真

仿真结果证明该方法作为高频地波舰载超视距雷达目标检测方法是有效的.

Abstract

In the HF ground-wave OTH radar

the movement of the radar brings about the spreading of the first order Bragg lines.It is difficult to pick up and measure the ship targets of the cover-up in the spread first order Bragg lines for the shipboard environment.In this paper

the causation of the spread spectrum are firstly analyzed

then it is suggested to use single null beam to pick up the ship targets and use pair null beam to detect targets direction.At last the method is simulated and the validity of detecting method of targets direction is attested for the HF ground-wave OTH radar.
