<title>Investigation of backscattering from elements of the vegetation canopy</title>

Abstract

While investigating the scattering from vegetation canopy it is necessary to know the scattering-law of electromagnetic waves on some single elements. Some principal problems that arise while studing the electromagnetic wave scattering from single leaf have been formulated in the papers [1,21. Two problems can be considered here: the influence of the moisture content and the shape of the leaf upon the scattering characteristic.This study represents some results of the experimental investigation of diffraction properties of vegetation canopy and its elements. These experimental components of the study included measurements of back-scattering cross sections (BCS), distribution of electromagnetic field in the near zone and radiation pattern. The measurement has been carried out in the millimeter range.
