摘　　要：针对箔条干扰动目标显示(MTI)雷达的问题,对MTI雷达功能原理及箔条干扰的性质作了简要分析,基于箔条云对电磁波的衰减特性,建立了在箔条走廊干扰条件下的雷达作用距离模型,利用箔条扩散模型对雷达作用距离模型进行实例仿真,分析了雷达作用距离与抛撒的箔条数量和箔条走廊厚度之间的定量关系,提出一种干扰MTI雷达的实用方法。Aiming at the problem of chaff jamming moving target indication （MTI） radar,this paper briefly analyzes the function ＆ principle of MTI radar and the characteristics of chaff jamming,establishes the range model of radar under the jamming condition of corridor chaff based on the attenuation characteristic of the chaff cloud to the electromagnetic wave, simulates the operating range model of radar through an example by means of the chaff spread model,analyzes the quantitative relationship between the operating range of radar and the thrown chaff quantity ＆ the thickness of the corridor chaff,presents a kind of practical method to jam the MTI radar.
