Mining subsidence monitoring using ALOS satellite data

InSAR (Synthetic Aperture Radar Interferometry) and D-InSAR technique is a more speedy deveolpping microwave remote sensing technique in recent years. The key problem that makes use of an InSAR data to carry on monitoring surface is: the biggest deformation monitor gradient of object is bigger than the biggest deformation gradient that InSAR can monitor, result in a serious decoherence phenomemon, the ALOS satellite L band data has a longer wavelength, its monitoring gradient also is more large, has an advantage in the mining area. This paper takes BinChang mine area in Shaanxi as a study region and interferes with data of the ALOS image, then get interference figure, deformation distribute figure, on this foundation, adopted the related question of accident monitor to carry on vs the mine area earth´s surface concerning the theory and the technique study.
