Abstract: We developed a ground-based polarimetric broadband SAR system which consists of a vector network analyzer, one dual polarized antenna, and an antenna positioner. It can be operated in a frequency range from 50 MHz to 20 GHz, with a scanning aperture of 20 m in the horizontal and 1.5 m in the vertical direction. Using the polarimetric GB-SAR system, we carried out evaluation measurements. It was applied to Cherry tree monitoring, and polarimetric information from the measured SAR data was interpreted. The frequency dependency of the polarimetric feature from the SAR was observed. The same system can be used for interferometric measurement. Our test showed that the system can detect a deformation of the surface of a wooden building at the accuracy of less than 1cm.
