摘要
本文借助于旋转椭球矢量波函数和平均场的理论,得到了非均匀扁旋转椭球粒子对偏振电磁波散射的准解析解,并利用所得理论公式给出了雷达气象上极为重要的在平行和垂直入射条件下,非均匀扁旋转椭球状海绵冰粒对雷达波的后向散射截面数值计算结果。在计算中认为海绵冰粒分二层,内核为纯冰扁旋转椭球,外层由冰水混合构成。
The solution to electromagnetic scattering by inhomogeneous oblate spheroidal particles is obtained for any polarized incident wave on the theories of spheroidal wave functions and average electric fields. And calculations are made for r?dar backscattering cross-section of a two-layeredspongy ice hailstone with an arbitrary size and condition. The nucleusof the hailstone is considered as an ice oblate spheroid and the shell isfilled with a mixture of ice and liquid water.
