In this paper, we present numerical simulations and indoor bistatic scattering measurements on scaled targets. The targets are vertical and/or tilted dielectric parallelepipeds representing the main forest elements (tree-trunks and primary branches) at VHF and lowUHF frequencies. They are placed above an aluminum circular plate to simulate a flat ground.(More)
A 3D coherent scattering model simulating the interaction of electromagnetic waves with forests has been developed. It is obtained by means of a full wave approach, based on an integral representation of the electric field [1]. A method of moments is used to solve the integral equation and compute the scattered fields related to the various scattering(More)
The interpretation of SAR data remains particularly difficult in the case of forests. Interferometric or/and polarimetric studies may enable us to retrieve some characteristics of the forest and identify the relevant scattering mechanisms involved in the global scattering phenomenon. A lot of numerical models have been developed to make the retrieval of(More)
In this paper, an electromagnetic scattering model based on the electric field integral representation is used to separate the scattering mechanisms involved in the interaction of an electromagnetic field with forested areas. This model is used to examine the different coupling effects between the main scatterers (trunks and branches) and those between the(More)
This paper presents fully polarimetric bistatic radar scattering measurements on groups of dielectric vertical and/or tilted square cross-sectional cylinders above a conductive circular plate in the frequency range of 6–18 GHz. The experiments have been conducted in the BABI facility at the French Aerospace Lab (ONERA). The imaging experiments consider an(More)
