摘要
近年来,随着经济的飞速发展,人类的生产活动加剧了部分地质灾害的产生,尤其是矿产行业,如何对矿区的地表沉陷进行有效监测成为众多学者的研究方向之一。随着雷达卫星的陆续布置,差分雷达干涉测量方法(D-InSAR)的高精度、全天候、成本低的特点使得它成为矿区沉降监测的重要手段之一。通过利用D-InSAR技术对试验区域的雷达影像进行双规差分法处理得到沉降信息,比对实际的测量数据,证明了D-InSAR技术在地表形变上的实用性。
In recent years,with the rapid progress of economy,human production activities have aggravated the emergence of some geological disasters,especially in the mineral industry,how to effectively monitor the surface subsidence of mining areas has become one of the research directions of many scholars.With the deployment of radar satellites,the differential radar interferometry method(D-InSAR)is high-precision,all-weather.The characteristic of low cost makes it become one of the important means of settlement monitoring in mining area.By using D-InSAR technology to process the radar image of the test area by double-rule differential,the sedimentation information is obtained,compared with the actual measurement data,which proves the practicality of D-InSAR technology in surface deformation.
