Ground-based synthetic aperture radar (GB-SAR) system has the advantage of continuous monitoring for a certain area day and night regardless of the weather condition. GB-SAR has broad application prospects in fields of mine, landslide, bridge settlement, earthquake deformation, and so on. The geometric mapping 3D matching between GB-SAR image and terrain data obtained in above fields is the key technology to combination of the system and the practical application. In this work, the relationship model between GB-SAR system and terrain data and the relationship model between GB-SAR system and SAR image are established. A 3D matching algorithm for geometric mapping based on range-azimuth condition is proposed, and the error characteristic in geometric mapping 3D matching process is considered. Finally, the effectiveness of our model and geometric mapping 3D matching algorithm is verified by the measured data.
