摘　　要：作战飞机在受到对方机载多普勒雷达锁定时通常投放箔条弹来干扰雷达的工作。针对这一特定场景,本文分析了箔条干扰的运动特性和雷达回波特性,建立了箔条干扰的数学和仿真模型,对雷达箔条干扰回波波形特性进行了模拟和仿真。研究成果有助于分析箔条回波对机载多普勒雷达的影响特性,对评估箔条干扰效果有着积极意义。The chaff cartridges are usually dispensed to interfere with the operation of the radars when the combat aircraft are locked by the hostile airborne PD radars. In view of this particular sce- nario, the motion and radar echo characteristics of the chaff jamming are analyzed, and the mathe- matical and simulation model is created to perform the simulation for the characteristics of the echo waveforms of radar chaff jamming. The simulation results contribute to analyze the characteristics of the chaff echoes that influence the airborne PD radars, having a positive impact on evaluating the effects of the chaff jamming.
