摘要：
A new terrain meshing method based on the ray-tracing algorithm is presented. In the propagation model, most of the transmission paths are focused in the area that between the transmitters and receivers. The main idea is to mesh the area containing both the transmitters and receivers into fine triangles while the rest area into larger triangles. The processing time of this developed method is half of the traditional method while maintaining the accuracy. A great number of simulations in an outdoor propagation environment were conducted to get these results. The developed terrain meshing method is of great significance in both theory and practice.
