| Abstract: | 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. |
