摘要: |
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,它将面上的二维问题降为一维问题,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椭球的反射波形,并讨论了它们的特性。 |

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