摘　　要：几种常用的室内定位技术均存在各自的缺陷,很难用于复杂室内环境。提出了一个基于射线跟踪技术的室内定位模型,通过跟踪从发射机到接收机之间的所有传播路径,得出有效的定位参数,从而进行高精度定位。最后实验仿真证明了模型的有效性。Several common indoor positioning technology had their limitations, so it was very difficult to deal with the complex indoor environment. This paper presented an indoor positioning model based on ray tracing technology. This model could gain the effective positioning parameters by tracking all the transmission path between the transmitter and the receiver, so it could conduct high-precision positioning. Finally, it was proved the availability of the presented model by simulation.
