倾斜及急倾斜煤层伪斜巷道放顶煤采煤法
Based on the research method,the paper also studied effect of distance between transmitter and receiver on propagation loss and RMS time delay spread of the electromagnetic wave in idealization model of incline tunnel.
文章详细介绍了仿真研究斜井巷道中电磁波传播距离对多径衰落和RMS时延的影响所采用的方法——射线跟踪法的原理和射线跟踪过程中射线方向的判断及射线代表的场强值的计算,在此基础上,在理想化的斜井巷道模型中研究了接收机与发射机间的距离对电磁波衰落及RMS时延扩展的影响。
