PD雷达导引头对箔条的建模与仿真

箔条作为无源电子对抗中的常用干扰材料,已被广泛用于雷达无源对抗系统中。文中对工作在脉冲多普勒体制下的雷达导引头箔条回波进行了建模,并且分析了箔条回波的时域和频域特性。基于箔条的整体运动特性,采用非递归滤波器法对箔条回波的幅度特性和功率谱特性进行了仿真实现,仿真结果与理论相符。箔条回波模型可用于PD雷达导引头干扰技术研究领域和PD雷达导引头抗干扰性能评估。

Modeling and Simulation of Chaff in PD Radar Seeker

Chaff is a useful jammed material with passive electronic confrontation,which has been used widely in passive countermeasure of radar system.This paper sets up the chaff model of PD radar seeker and analyzes the chaff echo in time domain and in frequency domain.Based on the overall movement characteristic of the chaff,non-recursive filter method is applied to the chaff echo amplitude characteristic and the power spectrum characteristic simulation.The simulation results are consistent with the theoretical ones.The chaff echo model will serve as the foundation for the research on the PD radar seeker jamming and anti-jamming technique.
