泡沫对主动毫米波雷达干扰效能分析

摘要

As a new method of passive interference,foam has obvious interference effects on active millimeter wave radar.From the aspects of scattering,reflection and absorption,this paper expounds the foam interference mechanism,according to the requirements of foam interference and target detection of active millimeter wave radar,the sheltered surface density of active millimeter wave radar and foam surface density between two points are calculated respectively,through the comparison of two surface densities,the interference effectiveness of foam is analyzed.Following conclusion of this article have important meaning for foams jamming efficiency evaluation and optimization of foams jamming tactics.%泡沫作为一种新的无源干扰手段,对主动毫米波雷达干扰作用明显。从散射、反射和吸收角度对泡沫干扰机理进行了阐述,根据主动毫米波雷达探测目标及泡沫干扰的要求,分别计算了主动毫米波雷达的遮蔽面密度和泡沫两点间面密度,通过两种面密度的比较,对泡沫的干扰效能进行了分析。该研究结论对泡沫干扰效能评估及泡沫干扰战术的优化具有重要的意义。
