Crown’s anisotropy of a tree and scattering the signals of navigation satellites frequency band L1

Autor: Podoprigora Vladimir, Sorokin Anotoly, Makarov Daniil, Kharlamov Dmitry

Publikováno v: E3S Web of Conferences, Vol 149, p 02005 (2020)

The model of interaction of signals from navigation satellites with the tree crown is considered. The contribution of the anisotropy of the dielectric constant to the cross section of radio wave scattering due to the orientational ordering of the bra

Forest dielectric characteristics for navigation satellites signals in L 1 range

Autor: Sorokin Аnatoly, Podoprigora Vladimir, Ponomarev Evgenii

Publikováno v: E3S Web of Conferences, Vol 75, p 01011 (2019)

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
