目前射线跟踪模型作为一种高精度的规划仿真传播模型在大中型城市覆盖重点区域的规划方案仿真验证中得到广泛应用,本文首先对射线跟踪模型的原理进行探讨,然后以WaveCall公司的WaveSight模型为例说明射线跟踪模型的应用方法。其结果有助于应用射线跟踪模型对规划方案进行精确验证,对规划工作有积极的参考和指导作用。 At present, the ray tracing model is widely used as a high-precision planning simulation propagation model in the simulation and verification of planning schemes covering large and medium-sized cities. In this paper, the principle of the ray tracing model is discussed first. Then, using WaveCall’s WaveSight model as Example illustrates the application of ray tracing model. The results contribute to the application of ray tracing model to accurately verify the planning scheme and have a positive reference and guidance for the planning work.
