摘要

针对高频雷达中存在的射频干扰空间结构非平稳特性

Fabrizio提出了一种干扰抑制方法.然而

该方法忽视了对目标信号相干积累的影响.本文分析了这种影响

在此基础上提出了一种新型的天线方向图综合算法

并进一步将其应用到射频干扰自适应对消中.仿真结果表明本文的方法较大地改善了高频雷达的工作性能.

Abstract

For the existing nonstationary spatial characteristics of radio frequency interference (RFI) in high frequency (HF) radar

Fabrizio came up with an interference rejection method.Nevertheless

the method ignored its side effects on the coherent integration of target signals.This effect is analyzed in this paper.On the basis of the analysis a novel array pattern synthesis algorithm is proposed and further applied to the adaptive interference cancellation in HF radar.Simulation results show that the performance of HF radar is greatly improved.
