基于方波卷积调制的灵巧干扰方法

摘要

For the problem of the conventional suppression jamming cannot obtain the processing gain,and the jamming effect will decline greatly under the situation of low power,and the application scope of the existed techniques is small.In order to solve this problem and gain better jamming effect,the smart jamming model a-bout the square wave with cycles was built up based on convolution modulation in the time domain,and a new signal form was designed,then the time-frequency characteristics and jamming effects were analyzed.The simu-lation result showed that square wave with cycles convolution modulation was able to achieve the deception and masking double jamming effects under the change of parameters.%针对传统压制干扰进入线性调频雷达无法获得脉压增益,在功率有限的条件下干扰效果会大幅下降和现有干扰方法应用范围较小的问题,提出了基于方波卷积调制的灵巧干扰方法.该方法在已有卷积调制干扰的基础上进行设计以获得较好的干扰性能,建立了基于时域卷积调制的灵巧干扰数学模型,提出了周期方波卷积干扰信号形式,分析了时频特性和干扰效果并进行了仿真实验.仿真结果表明,通过控制周期方波的各项参数可以达到欺骗和遮盖两种不同的干扰效果.
