Abstract: Interferometric synthetic aperture radar (InSAR) technology, with its advantages of high precision, large range and all-weather monitoring, has been widely recognized in the acquisition and inversion of surface elevation and deformation information and other applications, and has gradually developed into an indispensable technical means in the field of crustal deformation observation. However, the use of InSAR technology for crustal deformation observation cannot be achieved without the support of massive data. This is bound to create new challenges in the collection and interpretation of information. In recent years, the rapid development of machine learning has made encouraging achievements in remote sensing image processing. The attempt to combine the deep learning method with InSAR technology comes into being. The outstanding data mining ability of deep learning and the classification and prediction ability of target tasks will provide a new technical means for the data processing and application of InSAR crustal deformation observation. In this paper, the data processing and application of deep learning in InSAR crustal deformation observation are introduced, and its application prospect is prospected.
