The randomness and complexness of the heterogeneous soil make the soil’s relative permittivity vary throughout the survey region. The conventional data processing methods, which are based on the assumption that the soil permittivity in the test site is homogenous, yield inaccurate estimation of the roots’ positions and thus are not suitable for real GPR surveys. In this paper, we present a new data processing method for accurately positioning tree roots in heterogeneous soil. Numerical experiments are carried out to compare the results of the proposed method and the conventional method. The proposed method outperforms the conventional method in tree root positioning accuracy.
