Polarimetric and interferometric ground-based synthetic aperture radar (Pol-GB-SAR, In-GB-SAR) system has been developed. In this paper, two measurements of outdoor test sites in polarimetric and interferometric configurations are introduced and results are presented. In the developed In-GB-SAR system, the technique of differential interferometry is used to detect small changes at different times and under different conditions. Experimental results demonstrate that the system is very efficient and can detect small changes of the scale of 2 cm at the range distance of 5 m. Polarimetric analysis was done using the Pol-GB-SAR system with a coniferous tree as a target. The system has superior ability in polarimetric applications. Applying polarimetric and interferometric analysis which were developed for spaceborne and satellite radar remote sensing datasets, we can find detailed scattering mechanisms and detect deformations. The GB-SAR has a wide range of applications like environmental monitoring, resources management as well as monitoring of different natural phenomena
