摘要: 该文以一致性几何绕射理论(UTD)为基础,利用新提出的叠加模型对小型预警机主雷达相控阵天线的机体散射(包括螺旋桨散射)进行了分析,定量得出了这些散射的特点和变化规律,为天线装机后辐射性能预测与布局优化提供了理论依据。Abstract: Based on the Uniform Geometric Theory of Diffraction (UTD), the scattering of aircraft including propellers for the phased-array of the main radar is analysed by using of a new additive model of antenna. The variety and characteristic of the scattering is presented quantitatively. It can be used as a theoretical basis to dope out the radiation performance and optimize the arrangement of antennas.
