提出了一种基于射线跟踪方法的定位模型.该模型利用三维射线跟踪方法计算城市微小区复杂建筑物环境所形成的独特电磁特征,并建立定位数据库.实际定位时把待定位点实测的电磁信息与定位数据库中信息进行比较从而实现定位.仿真结果表明,该模型能有效克服常规方法难以克服的多径效应、非视距传播等不利因素,最终得到较高的定位精度.

This paper presented a positioning model based on ray-tracing method. According to calculate the unique electromagnetism characteristic in the complex environment of urban microcell by using 3D ray-tracing method, this model could generate a positioning database. The users' location estimates could be achieved by comparing the electromagnetism characteristic parameters recorded at location point with the positioning database generated by the computer. Simulation result shows that the model is effective and can obtain quite precise location result.
