Simulation Research on Multiple-false Targets Jamming Against Missile-Defense Guidance Radar

阐述了基于DRFM的多假目标干扰基本原理,分析了量化位数对噪声电平的影响。针对导弹防御系统中的典型制导雷达,分别对窄带系统和宽带系统进行了干扰仿真研究,分析了建立有效干扰对接收机灵敏度和干扰功率的要求,详细探讨了DRFM的量化位数对脉冲压缩及雷达一维成像性能的影响。最后提出了优化多假目标干扰效果的技战术建议。

The principle of DRFM multiple-false targets was expounded and the effect of DRFM quantization digit on harmonic amplitude was analyzed. Aiming at the missile-defense guidance radar, simulation research of jamming narrow and wide system was studied respectively. Then, the power requirement and receiver sensitivity for jammer were illuminated. Especially, the influence of quantization digit of DRFM on pulse compress and radar imaging was discussed detailedly. Lastly, several technical and tactical scenarios were put forward for improving jamming performance.
