| Abstract: | As flourishing space geodesy technologies, InSAR and BeiDou/GNSS have advantages in land surface deformation monitoring. By applying the two tools to carry out integrated measurements, their complementarity can be fully exploited to achieve the unification of high temporal resolution of BeiDou/GNSS and high spatial resolution of InSAR. This paper firstly introduces the basic principles of InSAR and BeiDou/GNSS for land surface deformation monitoring, focusing on the theoretical development of InSAR in the past two decades. Secondly, the latest progress of InSAR and BeiDou/GNSS integration and data fusion are reviewed. Then, the key issues and challenges faced by the land surface deformation monitoring applications are summarised. Finally, the future outlook of the deformation monitoring method integrating InSAR and BeiDou/GNSS is discussed. |
