摘要 根据多径信号的物理特性,从理论上推导了镜反射的多径误差简便模型,基于该模型进行了无线电干涉定位系统的多径误差分析.讨论了衰减因子、天线高度和水平距离等多径参数对测量结果的影响,并且进行了仿真计算和分析.结果表明,高精度定位必须考虑多径效应. A simple model of multipath error is proposed in condition of mirror＇s reflecting according to the physical characteristic of multipath signal. Then muhipath error analysis of radio interferometric positioning system （RIPS） is presented. The relationships between RIPS measurement and multipath parameters including attenuation factor, antenna height and horizontal distance of sensor nodes are studied. The results of simulation analysis verify that high precision localization must take multipath effect into account.
