高频地波雷达空域射频干扰抑制算法
Radio frequency interference suppression algorithm in the spatial domian for high-frequency radars
摘要
Abstract
Radio frequency interference suppression is a very important issue in applications of high-frequency surface wave radar.This paper proposes a new interference suppression algorithm which makes use of RF interference azimuth information on the basis of learning common RF interference suppression algorithms and spatial spectrum estimation.First,we apply the MUSIC algorithm to estimate the interference azimuth and obtains the interference`s signal space after the first Fourier transform;next,we use space decomposition to decompose the radar echo and obtain interference components;last,we subtract radio frequency interference components from the original signals.This algorithm can do great amount of RF interference suppression in actual data and get good results.关键词
