Ground-based synthetic aperture radar (GB-SAR) is a novel system applied deformation monitoring of buildings, mountains, and mining slopes with the advantages of high-resolution, large-scale monitoring, and fast image acquisition image interval. Most of current GB-SAR systems work in the high-frequency band, without the ability of vegetation penetration. So here, a GB-SAR system used for vegetated area is designed on the carrier frequency and other important parameters under the requirements for vegetation penetration, high-resolution and large-scale imaging. At last, the imaging ability and vegetation penetration ability of the designed GB-SAR system are assessed and verified through simulations and experiments.
