Ground Penetrating Radar Tomography Application to Study of Live Tree Trunks: Case Studies of Defects Detection
The report describes the use of the method of ground penetrating radar (GPR) ray tomography, applied to non-living objects , as a tool for studying the internal structure of trunk of living trees. Due to the lack of mechanical impact on the object of study and high resolution, GPR has an advantage in comparison with other methods of examining the state of trees , such as micro-drilling or acoustic tomography. Field experiments were conducted on different tree species in different states. The results obtained on healthy oak, dry spruce and chestnut with a cavity inside are described. Observations were made in summer of 2017. A two-channel GPR “Zond 12e” (“RadarSystems”, Latvia) with two 2 GHz antennas was used in experiment. GPR tomography is used to determine the distribution of permittivity in the trunk, which is directly related to the moisture of wood. Different parts of the trunk (bark, core, sapwood), as well as healthy and affected areas differ in humidity, so the method of GPR tomography allowed us to see both the structure of the trunk of a healthy tree, and the presence and dimensions of defects.
