旋转椭球体的瞬态电磁目标特性研究

Analysis of the Transient Electromagnetic Scattering Properties of An Ellipsoid of Revolution

本文针对旋转体金属目标，提出了改进的时域递推法，以计算其电磁脉冲响应特性，它将面上的二线问题降为一线问题，减少了计算量，以便于计算大尺寸目标。同时，用该方法计算了不同脉冲宽度激励下球的反射波形和不同长度棉球的反射波形，并讨论了它们的特性。

An improved method of Stepping-in-Time Procedure to compute the EMimpulse response properties of conducting bodies of revolution is provided in this paper. Bythis method, the two dimensions problem on surface is separated into one dimension problemand the time needed is shortened. It can be applied to large scale bodies target. Using themethod, the response waves of conducting sphere under different impulses length and the re-sponse wave of ellipsoid of different length are computed and discussed.
