摘要

强海杂波背景下进行相干源检测是舰载高频地波雷达(HFSWR)进行海上目标探测面临的一个主要问题.本文利用对称阵列法对阵列输出信号的协方差矩阵进行了重构

以解决相干源引起的降秩问题

在此基础上通过对背景噪声的预白化处理来抑制一、二阶海杂波.MUSIC算法对实录海杂波数据处理结果表明

这种方法可以从展宽的一阶海浪谱中分辨出各相干信号源的方位信息.

Abstract

Coherent sources detection on the background of strong ocean clutter is a main problem for high-frequency surface wave ship-mounted over-the-horizon radar to detect signals on the surface of the ocean.In this paper

a method of reconstructing the covariance matrix of the array data is presented

and then preprocessing the reconstructed matrix with pre-whitened MUSIC algorithm to get the azimuth information of the coherent sources from the widened first-order spectra.From results of the experiment on the collected data this processing method is effective.
