1·This paper realize the radar echo signal analysis and modeling from three aspects: contain the target echo, sea clutter, rain clutter and noise.

着重从目标回波、海杂波、噪声三个方面对雷达回波信号进行了分析和建模。

2·In the millimeter band, the variations are found of the power density of the rain clutter induced by back scattering with frequency and rain rate.

在毫米波段计算了雨区的后向散射引起的雨杂波功率密度随频率及降雨率的变化。
