| 摘 要： | 对海面和低空目标探测时,雷达电波传播过程中会受到雾体衰减和散射噪声的影响.分析平流雾和辐射雾对电磁波的衰减及雾体散射带来天线辐射噪声温度增加等特性,构建雾衰减影响下的雷达探测距离模型.仿真分析典型频率火控雷达在不同俯仰角、能见度和媒介属性条件下的雷达探测性能,结果表明较高频率雷达受雾的影响较大,雾区内含水量越多对雷达影...

| Abstract: | The radar detection performances for low altitude and sea surface radar targets will be influenced by the effect of fog attenuation and backscatter noise.The detection range model is presented based on the characteristics of fog attenuation,antenna noise temperature increase from advection fog and radiation fog.The detection performances of representative frequency fire control radars for the low altitude and sea surface targets are simulated on the conditions of different elevation angles,atmospheric visib... |
