【摘要】 现代电子战中传统箔条云的雷达散射截面积(RCS)会随扩散过程快速衰减,导致干扰效能显著降低,为了应对这一问题,提出通过有源干扰信号照射箔条云的研究思路。首先,结合箔条云的扩散模型,构建基于矢量传输理论(VRT)的箔条云电磁散射模型。其次,对典型有源干扰中的压制式干扰(射频噪声干扰)和欺骗式干扰(梳状谱干扰)进行样式仿真。最后,建立有源干扰信号照射箔条云的时变模型,并通过参数化仿真,分析不同照射条件下箔条云RCS的时变规律,研究不同干扰信号对散射增强效果的影响。仿真结果表明,通过有源干扰信号照射箔条云,可以显著提升箔条云的干扰效能。在有源照射箔条云的情况下,箔条云RCS峰值提升了170%,维持在峰值的时间增加了79%,消散至RCS为0所需的时间增加了94%。其中,梳状谱信号照射箔条云,散射效果更佳。有源干扰信号照射箔条云,可显著增强其整体电磁散射特性,为发展无源/有源复合干扰场景下的箔条干扰系统提供了理论依据。更多还原

【Abstract】 This study investigates an solution to combat the rapid radar cross section(RCS) decay of traditional chaff clouds in electronic warfare through active jamming signal illumination.We developed an electromagnetic scattering model based on vector radiative transfer(VRT) theory that incorporates chaff diffusion dynamics.The research simulated two primary active jamming techniques-barrage jamming(RF noise) and deception jamming(comb-spectrum)-and established a time-varying illumination model to analyze RCS evolution.Simulation results demonstrated significant performance enhancements:170% increase in peak RCS,79% extension of peak duration,and 94% slower RCS decay.Comb-spectrum jamming proved particularly effective for scattering enhancement.These findings confirm that active signal illumination can substantially improve chaff clouds’ electromagnetic scattering properties,offering valuable theoretical support for developing advanced hybrid passive/active jamming systems in modern electronic warfare scenarios.更多还原
