高频雷达中射频干扰的RD图表现机理与建模仿真
Analysis of the range-Doppler map appearance,modeling,and simulation of radio frequency interference in high-frequency radar
摘要
Abstract
Radio frequency interference(RFI)greatly threatens high-frequency over-the-horizon radar.This paper analyzes the range-Doppler(RD)map appearance,modeling,and simulation of the RFI.First,the relationship between the appearance of the RFI in the RD map and the RFI spectral features is analyzed.Second,the change in RFI spectra during the radar signal processing is discussed.Third,given the property of the white Gaussian noise passing through linear filters,the response functions of the filter are designed to produce various RFI spectra and RFI of the RD map appearance.Based on these studies,this paper proposes that RFI can be classified into three categories:single-frequency RFI,narrowband RFI,and wideband RFI.The reason for the RD appearance of the RFI is explained,and an RFI modeling method based on the convolution is proposed.Real data and simulation ex-periments demonstrate that our explanation of the RD appearance of the RFI is reasonable,and our proposed model can simulate many types of real RFI RD appearances.关键词
