摘　　要：本文针对靶场全球定位系统 (GPS)外弹道测试系统中的多路径效应 ,建立了多路径反射定位误差模型 ,给出了影响多路径误差的有关参量。Dealing with multipath errors in global position systems appearing in shooting range trajectory tests, the paper models the phase error due to multipath effect from a signal plane reflector. The bias and multipath correction for each satellite signal as a function of its azimuth and elevation is provided. An analysis of the most important features of the multipath error is provided through Matlab simulation.
