基于双极化天线载噪比测量的GPS多径检测

GPS Multipath Detection Based on Carrier-to-Noise-Density Ratio Measurements from a Dual-Polarized Antenna

Sanghyun Kim, Halim Lee, Kwansik Park

摘要:

在这项研究中,全球定位系统(GPS)的多径检测的基础上进行的载波噪声密度比,C/N 0,通过双极化天线测量。由于右旋圆极化(RHCP)天线对直接从GPS接收的信号敏感,而左旋圆极化(LHCP)天线对单反射信号敏感,因此RHCP和LHCP测量值之间的C/N 0差用于多径检测。一旦我们在低多径位置收集了GPS信号,我们就计算C/N 0差以获得可用于检测从另一位置接收的多径GPS信号的阈值。通过光线跟踪仿真验证了结果。

英文摘要:

In this study, the global positioning system (GPS) multipath detection was performed based on the carrier-to-noise-density ratio, C/N0, measured through a dual-polarized antenna. As the right hand circular polarization (RHCP) antenna is sensitive to the signals directly received from the GPS, and the left hand circular polarization (LHCP) antenna is sensitive to the singly reflected signals, the C/N0 difference between the RHCP and LHCP measurements is used for multipath detection. Once we collected the GPS signals in a low multipath location, we calculated the C/N0 difference to obtain a threshold value that can be used to detect the multipath GPS signal received from another location. The results were validated through a ray-tracing simulation.
