【摘要】：InSAR （Synthetic Aperture Radar Interferometry，合成孔徑雷達干涉測量）及D-InSAR技術是近年來發(fā)展比較迅速的微波遙感技術，它具有全天候、全天時、覆蓋面廣、高度自動化和高精度監(jiān)測地表變形的能力，已成為具有很大潛力的空間對地觀測新技術。根據(jù)差分干涉原理，D-InSAR技術用于地面形變監(jiān)測可以獲得地表分辨單元的微小形變，理論上可達到毫米級精度。該技術用于煤礦沉陷監(jiān)測，受到地面沉陷量級大、頻繁的地面活動、嚴重的時間去相干等因素的影響，如何有效地利用獲取到的干涉信息對煤礦進行不同方面沉陷監(jiān)測是一個亟待解決的問題。 基于雙軌法D-InSAR技術對礦區(qū)地面沉降進行詳細監(jiān)測與分析。以兗州州礦區(qū)為實驗區(qū)，對獲取的礦區(qū)5景數(shù)據(jù)進行干涉對優(yōu)化選�。恍纬闪藢嵱没倪m合于礦區(qū)沉降監(jiān)測的D-InSAR數(shù)據(jù)處理流程，基于該數(shù)據(jù)處理流程對優(yōu)化干涉對進行干涉處理，獲取了兗州礦區(qū)的地面沉結果并進行了分析與解譯，，分析了礦區(qū)沉降的時空變化趨勢；采用礦區(qū)地面沉降實測數(shù)據(jù)，對InSAR沉降監(jiān)測結果進行精度驗證與分析。實驗證明采用L波段的雷達數(shù)據(jù)進行雙軌法差分干涉測量是進行礦區(qū)地面沉降監(jiān)測的最佳手段之一。
[Abstract]:InSAR synthetic Aperture Radar Interferometry. Synthetic Aperture Radar interferometry (SAR) and D-InSAR are the rapid development of microwave remote sensing technology in recent years, it has all-weather, all-day, wide coverage. The ability to monitor surface deformation with high automation and precision has become a new space-to-earth observation technology with great potential. D-InSAR can be used to monitor the ground deformation and obtain the small deformation of the surface resolution unit, which can achieve millimeter precision in theory. This technology is used in the coal mine subsidence monitoring, and it is subject to large ground subsidence. Because of frequent ground activity and serious time decoherence, how to effectively use the interference information to monitor the subsidence in different aspects of coal mines is an urgent problem to be solved. Based on the dual-track D-InSAR technique, the ground subsidence of the mining area is monitored and analyzed in detail. Taking Yanzhou mining area as the experimental area, the five scene data obtained from the mining area are selected by interference optimization. A practical D-InSAR data processing flow is formed, which is suitable for mining subsidence monitoring. Based on the data processing flow, the optimal interference pair is processed. The results of ground subsidence in Yanzhou mining area are obtained and analyzed and interpreted, and the temporal and spatial trends of subsidence in Yanzhou mining area are analyzed. The measured data of land subsidence in mining area are used. The accuracy of InSAR subsidence monitoring results is verified and analyzed. It is proved by experiments that using L band radar data for differential interferometry is one of the best methods for monitoring land subsidence in mining area.
