一种部分森林覆盖环境电波传播特性预测方法
A Method of Wave Propagation in Partly Forest Environment
摘要
Abstract
The parabolic equation method based on dynamic grid was proposed for the medium which was inhomogeneous in partly forest environments.The wide angle parabolic equation method was used to predict the wave propagation.The dy-namic grid technology was introduced to solve the accuracy and timeliness of parabolic equation solution.By simulations, the efficiency of the new method in partly forest environments was discussed.The results showed that the parabolic equa-tion based on dynamic grid could reduce the computational time greatly compared with the uniform fine grid in the case of similar accuracy,and could have higher accuracy compared with the uniform coarse grid.关键词
