Use of ground-penetrating radar as a non invasive method to study the growth, dynamic and biomass contained in the roots of typical trees of tropical rainforest.

The objective of this study is to observe the application and performance of the ground penetrating radar (GPR) as a non invasive method of estimating the biomass and distribution of the roots of Brazilian forest trees planted in location propitious for radar investigation. The GPR 2D profiles where collected with 200 MHz shielded antennas, with the intention of obtaining information about the deeper roots. The results presented in the form of GPR signal amplitude maps show the behavior of the plant’s roots, indicating the position and the average volume of the Guapuruvu roots with precision.
