利用多种技术手段对InSAR监测成果进行精度验证的研究
Research on Accuracy Verification of InSAR Monitoring Results by Using Various Technologies

针对基于InSAR技术大面积地表沉降监测成果精度验证困难的问题，本文主要研究利用邻近点法与升降轨融合技术相结合的方式对InSAR监测成果进行精度验证，邻近点法可有效检验局部区域成果精度，升降轨融合技术可对不同组SAR数据处理结果进行相对校验，两种方法相结合有效解决了水准点、GNSS监测点少而导致验证不完整的问题。
In view of the difficulty in verifying the accuracy of large-scale ground subsidence monitoring results based on InSAR technology, this paper mainly studies the method of combining the adjacent point method with the lifting rail fusion technology to verify the accuracy of InSAR monitoring results. The adjacent point method can effectively verify the accuracy of local results, and the lifting rail fusion technology can relatively verify the processing results of different groups of SAR data. The combination of the two methods effectively solves the problem of incomplete verification caused by a few leveling points and GNSS test points.
