Ground-Based ArcSAR Interferometry and Sensitivity Analysis

Compared with the linear-scanning ground-based synthetic aperture radar (GB-SAR), ground-based arc synthetic aperture radar (GB-ArcSAR) can achieve a larger range of scanning and is gradually being used. GB-ArcSAR can use both vertical and horizontal baselines to achieve interferometry. This paper introduces two interferometric measurement methods of GB-ArcSAR and carries out sensitivity analysis. It is verified based on simulation data.
