关于InSAR沉降监测结果精度比对的方法研究

Research on the Method of Precision Comparison of InSAR Settlement Monitoring Results

本文主要在InSAR沉降监测结果比对中常用的均值法的基础上,提出了一种新的InSAR与水准测量成果比对的方法,并且应用研究区域的实际数据成果对两种方法进行了实验分析。该方法主要思想是在均值法的基础上将PS点与水准点之间的距离因素纳入考虑,通过距离对PS点对InSAR成果值的贡献程度进行修正。研究表明,距离权值法相比于均值法拥有更高的精度和可靠性。

This paper mainly bases on mean value method,a commonly used method of settlement monitoring results in InSAR in comparison,puts forward a new method of InSAR leveling and alignment results,and use the actual data of application research area for the experimental analysis of two kinds of methods.The main idea of this method is to take the distance between the PS point and the standard point into account to correct the contribution of the PS point to the InSAR value.The results shows that the method has higher accuracy and reliability than the mean value method.
