摘要

为解决卫星导航信号中提取多径分量困难的问题

提出了一种利用相关曲线偏差(SCB)分离导航卫星多径信号的方法(MSCB)。首先建立包含多径分量的接收信号模型; 然后分析SCB偏差与多径信号幅值、延迟与相位之间的关系

得到不同多径延迟条件下两种不同的SCB偏差形状; 最后通过SCB拐点估计出多径信号参数。基于北斗和GPS导航卫星的实验结果表明:MSCB方法能够有效地将来自地面与卫星自身的多径分量(或类似多径分量)特征参数提取出来

将多径分辨率从米级提高到分米甚至厘米级别

其估计标准差仅为传统多径估计延迟锁定环路算法的1/6左右

为未来多径信号的建模与分析提供了一种新的有效方法。

Abstract

A multipath S-curve bias(MSCB)method to isolate multipath signals based on S-curve bias(SCB)is proposed to solve the complexity of extracting the multipath component from the signals of navigation satellite. A model for received signals that contain multipath components is built. Then both the relationship between SCB and multipath amplitude and the relationship between phase and delay are analyzed. Two different SCB curves are obtained under different multipath delay conditions. The multipath parameters is finally estimated from the turning points of the SCB curves. Experimental results based on Beidou and GPS signals show that MSCB effectively extracts characteristic parameters of multipath component(or multipath like)from the ground or satellite itself

and the multipath resolution is improved from meter to decimeter or even centimeter level

and that the standard deviation of MSCB estimation is only one-sixth of that derived from the traditional multipath estimation delay locked loop algorithm. It is concluded that MSCB may provide a new approach to model and to analyze multipath signals in the future.
