Abstract (English):
A radar method for surveying forests based on GPR technology is proposed, which allows measuring the density of the forest environment with an error of ±5%. The forest is irradiated by a georadar installed on a car. Counting the number of reflections from tree trunks (hyperbolas) in a given area allows you to quickly and reliably determine the number of trees per unit area (ar) and recalculate into forest density. A clearer radargram of reflections from tree trunks was obtained with vertical polarization, i.e. the signal reflected from the tree trunk is higher when the polarization of the probing electromagnetic pulse is parallel to the trunk.
