Deep underground space positioning method based on InSAR technology

The invention discloses a deep underground space positioning method based on an InSAR technology. The deep underground space positioning method specifically comprises the steps of obtaining earth surface time sequence deformation and accumulated deformation results based on a satellite platform SAR, and inverting an underground engineering azimuth angle based on earth surface time sequence deformation data and an underground space inversion algorithm based on an IPIM model. According to the method, the InSAR technology and the IPIM model are combined, the deep underground space inversion precision can be effectively improved, the underground space azimuth angle is determined in advance based on the texture information of the earth surface deformation of the time sequence LOS, needed inversion parameters can be reduced, the inversion efficiency can be improved, and the method is suitable for large-scale popularization and application. The hybrid intelligent genetic particle swarm optimization algorithm is adop
