Radar can be used as a tool to non-invasively image the inside structure of tree trunk in the inspection. Imaging by radar only with reflection measurement has already been established. However, we developed a framework of the inspection that combines reflection and transmission measurements. In our way the quick assessment by transmission measurement and detailed inspection by reflection imaging became possible. In addition the permittivity of tree trunk can be estimated from the transmission measurement data, which is required for reflection imaging. Consequently, we can improve the quality of reflection imaging by using the estimated permittivity. In the present paper, our framework for the tree inspection by radar is illustrated and the improvement in the quality of reflection imaging is demonstrated.
