Abstract: 根据Vondrak滤波法在信号的截断频带上具有较高信号分辨率的特点,将Vondrak带通滤波法应用于全球定位系统(GPS)结构变形监测中以分离结构振动和多路径效应的影响。对GPS实际观测资料进行分析,结果表明:采用该方法不仅能从坐标序列中成功提取结构振动信息,也能正确分离载波相位双差观测值的残差序列中的结构振动和多路径效应影响,因而在提高GPS定位精度上具有较大的应用潜力。
Vondrak bandpass filter,which has good signal resolution over its signal truncation frequency band and is effective in separating structural vibrations from global positioning system(GPS) multipath effects,was applied to GPS structural deformation monitoring.Real GPS observations were used to test the performance of the proposed filter.The results show that the method has the potential to improve the quality of GPS results,which can successfully extract the desired vibration signals from the point coordinate series and separate the structural vibrations and multipath signals from the double-difference carrier-phase observation residuals series.
