摘要
InSAR技术是当前从卫星雷达遥感获取的对地观测数据中提取地形信息最主要的技术手段。本文以贵州省普安县罗马山为研究区,收集了2017年4月16日至2018年8月5日共10景ALOS PALSAR2数据,生成9个干涉对,以形变时间序列的方式对研究区中的滑坡体进行形变监测分析。同时,收集兴仁县2017年4月至2018年8月降雨量信息,通过与形变时间序列的对比分析,可发现降雨量与形变的高度相关性,这对滑坡灾害的预防具有重要意义。
In SAR technology is the most important technical means for extracting topographic information from Earth observation data obtained from satellite radar remote sensing.This paper chooses Luomashan,Xingren County of Guizhou Province as a research area to collect 10 ALOS PALSAR2 images from April 16,2017 to August 5,2018,and generates 9 interference pairs,which are transformed into time series to perform deformation monitoring analysis of the landslide body.At the same time,the rainfall information from April 2017 to August 2018 in Xingren County was collected.Through the comparative analysis with the deformation time series,the high correlation between rainfall and deformation can be found,which is of great significance for the prevention of landslide disasters.
