二维散射问题的一个完整的时域解

A complete solution to 2-D scattering problems

本文研究了利用卷积直接求解瞬态散射远场的方法,得到二维散射问题完整的时域解,通过计算实例与严格理论解的比较,表明算法的正确性,文中给出几种规则散射体的RCS和瞬态散射远场的计算结果.

In this paper a method for directly obtainning transientscattering far field in the time domain using convolving technique is presented, from which 2-D completescattering solution is reached. Some results on RCS and the transient far field for several canonical scattcrers are given.
