摘要
基于Laws-Parsons雨滴尺寸分布模型,研究了降雨对毫米波信号传播衰减的影响,分析了毫米波信号的降雨衰减与降雨率之间的关系。在此基础上,定量分析了降雨对毫米波雷达导引头最大作用距离、舷外有源诱饵对毫米波雷达导引头的等效RCS数值的影响,研究结论对复杂气象环境下毫米波雷达导引头的作战使用具有重要意义。
Based on Laws-Parsons raindrop size distribution model,the influence of rainfall on millimeter-wave signal propa⁃gation attenuation is studied,and the relationship between rainfall attenuation and precipitation is analyzed.On this basis,the ef⁃fects of rainfall on the maximum range of millimeter wave radar seeker and the equivalent RCS value of the outboard active decoy on millimeter wave radar seeker are quantitatively analyzed.The research conclusion is of great significance to the operation of millime⁃ter wave radar seeker in complex meteorological environment.
