Abstract
After achieving the goal of TV digitalization, having an experience of the great earthquake, the government is promoting development and enhancement of the disaster prevention communication network across the nation. The field estimations is significantly important to design high-performance radio communication networks such as fire and disaster prevention wireless communication network. We have developed and proposed the discrete ray tracing method (DRTM) to compute electric field distributions along the land surface structure. We discuss on the discretization of the terrain surface, dividing by observation plate length, the equal interval size of linear piece wise strips. And we consider the alternative plate length for the shape of the surface, for example, short length is only for the mountain summit and long length is for the other. That enables us to reduce more computation time, adjusting the observation point length, keeping an accuracy of calculated output data.
