为计算任意曲面上天线间的隔离度,提出一种射线寻迹的新算法——最小夹角法.首先对任意曲面表面进行三角形网格剖分,并按照文中要求的格式生成模型表面网格数据;用文中提出的“最小夹角法”对上述网格数据进行处理,从而达到快速准确地找出任意曲面上、任意两点间的短程线.求解了位于圆柱体、椭球体及任意组合体上任意两点间的短程线长度,验证了“最小夹角法”的准确性.
In order to calculate the isolation between antennas on an arbitrary surface, a new ray tracing algorithm, the minimum angle method, is proposed.At first, triangulate the surface of an arbitrary surface and generate the surface grid of the model according to the required format Data, the proposed method of “minimum angle method” is used to process the above grid data, so as to find the geodesic between any two points on any surface quickly and accurately. The length of the geodesic between any two points in any combination verifies the accuracy of the “minimum angle method”.
