飞机目标通常抛撒箔条弹来干扰雷达的工作。针对这一作战场景,首先研究分析了飞机与箔条的运动特性和雷达回波特性,导出了对于地基防御雷达而言,箔条弹在时域上可视为点目标、在多谱勒域上可不考虑其多谱勒展宽效应的结论。在此基础之上,建立了箔条干扰的数学和仿真模型,模拟并分析了飞机加箔条的运动状态和雷达回波特性。研究成果有助于揭示箔条干扰的雷达特性,评估箔条的干扰效果。

Aircraft targets often dispense chaff to jam radar＇s working.Aiming at this scene,firstly,the motion characteristics and electromagnetic scattering properties of the plane and chaff are analyzed.According to the analysis,it is concluded that for the ground based radar,the chaff cloud can be regarded as a point target in the time domain and its Doppler stretch can be ignored in the frequency domain.On this basis,the correlative mathematical model and simulation model are established.Then,the state of motion and the characteristics of radar echo of the plane with chaff are simulated.The production is useful to explain the electromagnetic properties and evaluate the effect of chaff jamming.
