摘　　要：首先建立了外源信号传播的仿真模型,由此推算出直达波信号与多径反射信号的强度,并与实际测量情况进行了比较验证,然后将直达波强度与多径信号强度作了对比分析,得出直达波的存在对布站的影响,从而为接收站的布置问题提供了参考依据。This paper firstly established emulation mode of the transmission of outer radiant point signal, therefore calculated intensity of direct wave signal and muhipath signal, and compared it with practical measure value. Then we analyzed direct wave signal and multipath signal, educed the impact of direct wave signal to laying station, thereby provided reference warrant for laying of receiving station.
