摘要 多路径误差在绝大部分应用中,其测站间相关性很弱,不能通过差分观测得到有效削弱,成为高精度GPS动态变形监测中的主要误差源。针对GPS多路径误差的特点,结合具有良好多尺度分解能力的经验模式分解方法(EMD)和具有良好盲分离能力的独立分量分析(ICA)方法,提出带参考信号的EMD-ICA方法来削弱多路径效应的影响。应用实例的结果证明了该方法的有效性。 Multipath error is a main influence on high-precision GPS dynamic deformation monitoring results as it is difficult to be mitigated by difference observation in most of applications. A method called EMD-ICA with reference signal is proposed, It combines empirical mode decomposition(EMD) with independent component analysis(ICA). The test shows the effectiveness of this method.
