| Abstract: | Ground-based Synthetic Aperture Radar Interferometry (GB-InSAR) is a new deformation monitoring technology with advantages of high automation,all-day and all-weather monitoring,high resolution and high precision.In order to promote the application of GB-InSAR in the monitoring of islands and coastal zone in China,the technical principles and monitoring processes of GB-InSAR were summarized.Key techniques such as image registration,interferogram and coherence map generation,interferogram filtering,phase unwrapping,atmospheric phase correction,frame reference determination and geo-coding were analyzed.The results showed that GB-InSAR effectively integrated stepped frequency continuous wave technology,synthetic aperture radar technology and radar interferometry.It had a broad application prospect in collecting deformation information of target.The research and application of GB-InSAR in islands and coastal zone monitoring should be actively promoted in China.It would provide strong technical support for the management of islands and coastal zone. |
