| 摘 要： | 入射反弹射线法（SBR）在室内场强预测中是一种常用的方法。文中采用镜像法计算室内场强分布，镜像法是对SBR法的简化。用这种方法计算室内天线在空间中任意一点的电场时，找出天线上每一个电流元在各个墙体的镜像源，用镜像源代替墙体的影响，将天线和所有的镜像源产生的电场叠加在一起即可得到该点的场强。经分析，在简单的环境中，与SBR相比，镜像法可以大大提高效率，同时经过计算实例验证了镜像法的准确性。

| Abstract: | Shooting-and-bouncing-ray(SBR) is an approach for radio wave propagation in indoor environments.In this paper,we use image approach which simplifies SBR to calculate field distribution of indoor antenna.By finding images of indoor antenna and summing the contuibutions of these images coherently,we can obtain the total received field at a receiver.This method has high-speed advantage in simple circumstance compared with SBR by analyzing.In addition,We verify this approach by comparing the numerical results i... |
