“…The complexity of modeling the propagation of radio waves in the forest is known [1,2,7,8]. The prospects of using the signals of navigation satellites of the L1 range as a universal instrumental measuring resource and adaptive modeling of the forest stand, taking into account its layered structure, are real.…”

A scattering and attenuation processes of navigation satellite signals in the forest interaction with tree trank and crown layers a tree stand are presented. The influence of the boundaries soil - tree stand – crown - air on the characteristics of radio signals scattering after interaction with forest is considered. Structural and electro physical features of tree stand elements in the processes of interaction with signals of the L 1 range and experimental data on signal transformations the forest are analyzed.

“…The dielectric permittivity of leaves and needles of different types of forests depending on humidity varies for the real part of ɛ' from one to 40 and for the imaginary part of ɛ'' from 0.2 to five [6][7]. The electro physical model of tree stand as an aggregate of individual trees with a relatively low density of tree elements distribution in the volume of a stand suggests taking into account the dielectric properties of individual tree elements in a given frequency range.…”

A structural dielectric model of the forest is presented taking into account the wood Biomass distribution. The multi-scale structural formations of the individual trees and the stand as a whole as a hierarchical system of non-interacting components of the mixed dielectric are discussed. Layers of crowns and trunks are distinguished as anisotropic dielectric media with gradient boundaries. The possibility of using the orientation parameter of the order of branches in the crown layer to estimate the gradients of the effective permittivity of the inhomogeneous distribution and its spatial anisotropy is analyzed. A comparative analysis of the features of the effective dielectric permittivity of pine and birch forests is carried out. The possibilities of using a layered anisotropic dielectric forest model to describe the transformation of GPS and GLONASS signals in order to restore the biometric characteristics of the forest are considered.
