基于天线辐射方向特性的射线跟踪加速算法
Ray Tracing Acceleration Algorithm Based on AntennaRadiation Pattern
摘要
Abstract
For the forward ray tracing problems,the generation scheme of the ray-tube is proposed,which can simplify the meshing procedure and extremely reduce its complexity. Then,a method for computing the relation between points and grids is given,which can easily choose the required grids and grid points out and compute their geometric parameters. In con-junction with the antenna radiation pattern,the computing efficiency is improved by selecting ray-tubes satisfying the calcula-tion requirements. Finally,numerical results show that the algorithm can greatly promote the calculation efficiency of forward ray-tube tracing for antennas possessing good directivity.关键词
