Ultrashort-baseline Persistent Scatterer Radar Interferometry for Subsidence Detection
This paper presents an improved approach of multi-temporal interferometric synthetic aperture radar (InSAR) for detecting land subsidence phenomena by using time series of high resolution SAR images. Our algorithm extends the capability of the temporarily coherent point (TCP) InSAR technique proposed previously to detect subsidence even in the case of a small number of SAR images available for ...
متن کاملRadar Interferometry for Mining Subsidence Monitoring
Coal mining activities all over the world often introduce serious environmental impact to the local regions, such as the occurrence of land subsidence. Conventional subsidence monitoring is done by precision leveling and GPS surveying. However, recent studies show that differential interferometric synthetic aperture radar (DInSAR) is capable of monitoring land subsidence at sub-cm accuracy. In ...
متن کاملDifferential Radar Interferometry for Mine Subsidence Monitoring
The history of mining disasters includes cases of subsidence and collapse into workings, and also a number of inrushes into underground mines, where deficiencies in surveying, or in maintenance and interpretation of plans, were prime factors. The most recent incident in Australia was at the Gretley Colliery in NSW, in 1996. The most recent such incident in the USA was at the Quecreek Mine in So...
متن کاملDifferential Radar Interferometry and Its Application in Monitoring Underground Coal Mining-induced Subsidence
Ground subsidence due to underground coal mining threatens the safety of surface infrastructure such as buildings, roads, bridges, powerlines and telecommunication cables, and can cause environmental problems such as water pollution, cessation of stream flow, and so on. Monitoring the spatial distribution of surface deformation may be helpful for land-use planning, land reclamation, safety and ...
متن کاملSatellite radar interferometry for mine subsidence monitoring
Australia is one of the world’s leading mineral resource extraction and exporting nations. Underground mining can cause ground surface displacement, which may in turn have serious impacts on the environment or man-built facilities. This paper describes the results of a study into the feasibility of surface subsidence (caused by underground coal mining) monitoring using differential interferomet...
