The muitipath error of gps receiver and the analysis of performance of narrow - correlation 接收机多径误差及窄相关性能分析
In the radar elevation coordinate , the multipath effects are more severe , which cause periodic peak error in the target height measurement 在雷达俯仰角(目标高度)方向上多径误差的影响尤为严重,使得目标高度的测量误差表现为周期性的尖峰误差。
When low elevation targets arc tracked using the monopulse radar , the multipath effects including the specular reflect and diffuse reflect degrade severely the tracking performance 雷达跟踪海面低空目标时,由镜面反射和漫反射引起的多径误差严重影响雷达的跟踪性能。
Most of error sources can be eliminated by double differencing due to the short antenna seperations within gps based attitude determination system , multipath is the dominant error source Gps姿态测量中,大部分误差源可通过双差得到抑制或降低,多径误差成为主要的误差源。
In this dissertation , the theory and realiztion of gps based attitude determination technique are studied , multipath effects on gps observables and carrier phase multipath mitigation are also analyzed 本文研究了gps实时姿态测量技术的理论及实现,并分析了多径效应对gps观测量的影响及载波相位多径误差抑制。
