Abstract

The method for determining the stocks of stem wood using the measurement data of the linear attenuation coefficients of signals navigation satellites L1 range and general taxometric characteristics of the forest is presented. A variant of determining the stocks of stem wood by differences in contributions to the attenuation by layers of crowns and trunks is considered, taking into account the coordinate referencing of the trajectory of the probe signal in the tree stand.

Highlights

The task of restoring stocks of stem wood by remote method using navigation satellite (NS) signals has the prospect of non-contact obtaining the average value of the crosssectional area of trunks in the forest area
Instrumental methods for determining the stocks of stem wood using NS signals involve measuring the coefficients of linear attenuation in a representative array of the forest test site
Moving navigation satellites in the range of elevation angles from 10° to 90° and azimuth from 0° to 360° and the variable height of the antenna location allow to conduct a three-dimensional scan separately of the crown volume and the mixed volume of the crown and trunk layers

Summary

Introduction

The task of restoring stocks of stem wood by remote method using navigation satellite (NS) signals has the prospect of non-contact obtaining the average value of the crosssectional area of trunks in the forest area. This indicator is determined based on the results of taxation using the regularities of the distribution of phytomass in the forest stand. The structure of the stand forest as a mixed dielectric made of air and trees is spatially inhomogeneous in the distribution of tree elements and trees themselves, has a layered structure [1,2]. The study of the possibilities of using radio scanning of the forest with NS signals is an urgent task
