| 摘 要： | 利用拉氏变换和卷积的方法,导出了求解3-D和2-D时域散射远场的形式上统一的公式,使得2-D情况成为3-D的一个特例,这给编制求解时域散射远场的通用程序带来方便.同时这种3-D的近场-远场变换算法和原来的算法比较并没有增加计算量.对简单形体的计算验证了算法的可行性.

| Abstract: | A unified solution for both 2-D and 3-D scattering problems are presented by using Laplace Transformation and convolution technique, which makes 2-D problem a special case of 3-D problems. It provides convenience for programming to obtain time domain scattered far-field. Compared with previous near -zone to far-zone transformation method,no additional computation effort is needed in this methed. Volidity of this method is verified through computation examples of simple objects. |
