Mining region detection method cooperating with SAR image phase, intensity and coherence information

The invention discloses a mining region detection method cooperating with SAR image phase, intensity and coherence information. The mining region detection method comprises the following steps of: performing focusing processing, main and auxiliary SAR image registration and resampling preprocessing on acquired initial SAR data in combination with an external DEM; and performing mining region detection on the registered SAR image by using SAR image phase, intensity and coherence information to obtain a mining region deformation result, a mining region SAR intensity change detection result and a mining region SAR coherence detection result, and accurately identifying the coal mining region in the research region by combining the three processing results. According to the mining region detection method, the phase, intensity and coherence information provided by the SAR image is utilized, and large-range detection and accurate identification of the mining region can be realized.
