基于改进的小波-矩阵法实现雷电干扰抑制
Lightning Interference Suppression Based on Improved Wavelet-Matrix Combined Algorithm
摘要
Abstract
HF surface wave radar(HFSWR) works in high frequency band,which is an extremely complex electromagnetic environment.Lightning interference,as the main form of transient interference,may badly affect the detection performance of HFSWR,when detecting flying targets.Compared with traditional anti-interference methods,the previous wavelet-matrix combined method has the advantages of high positioning accuracy and low complexity of algorithm,but it is limited by its single application.Based on the applicable conditions of combined method,lightning interference is classified and suppressed separately,and an improved wavelet-matrix combined algorithm is proposed in this paper.The simulation results show that it can suppress various lightning interferences,minimize the noise floor of the Doppler domain,and improve HF radar's resistance of lightning interference effectively.关键词
