靶场GPS载波相位多路径误差建模与仿真

MODELING AND SIMULATION OF CARRIER WAVE MULTIPATH PHASE BIAS ON SHOOTING RANGE GPS POSITION MEASUREMENTS

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.
