摘　　要：本文介绍了对扁椭球形雨滴和冰（雹）粒散射能力的实验模拟和测量技术，报告了一个系列扁水（冰）椭球后向散射截面的实验测量结果；并用扩张边界条件法（ＥＢＣＭ）计算出相应的理论值，用Ｍｉｅ公式计算出等容积球形后向散射截面。将实验结果与理论计算作了综合对比分析，得到了若干有用的结论。This paper describes the experimental simulation and measuring technique of the scattering from oblate water and ice ellipsoids. The measuring results of the backscatter cross-section are given for a series of oblate ellipsoids. The backscatter cross-sections of oblate allipsoids and those of the corresponding sphere of equal valume are calculated using the Extended Boundary Condition Method and Mie formula respectively. The experimental data obtained are reliable. The experimental data are compared with theoretical results. Some useful conclusions are thus drawn.
