Coal fire area surface morphology change is one of the available indicators of coal fire monitoring and analysis of due to the mining area surface serious to coherent noise, the spaceborne Into aperture radar interferometry technique is applied to coal fire area of surface deformation detection more difficult combining with the characteristics of surface deformation in coal fire area, use 4 band - 45 ( - 4-! Differential interference in the data processing, the baseline is estimated based on the interference fringe frequency precision, using adaptive filtering method to reduce to the coherent noise Reference terrain effects in removing the ground phase and phase, for coal fire area surface deformation research shows that: the surface deformation and coal fire burning has certain The correlation between, through the analysis of the surface deformation helps burning of underground coal fire situation judgment Using differential interference (-! Technology to detect coal fire area
