【摘要】：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。
[Abstract]:In view of the problem that the traditional suppression jamming can not obtain pulse compression gain in LFM radar, the jamming effect will be greatly reduced under the condition of limited power, and the existing jamming methods will have a small range of applications. A smart interference method based on square wave convolution modulation is proposed. This method is designed on the basis of the existing convolution modulation interference to obtain better interference performance. The mathematical model of dexterous interference based on time domain convolution modulation is established, and the periodic square wave convolution interference signal form is proposed. The time-frequency characteristic and interference effect are analyzed and simulated. The simulation results show that two different interference effects can be achieved by controlling the parameters of periodic square wave.
