An Automatic Choice of Simple Geometric Shapes for Modelling Terrain Diffraction Phenomena

Résumé

When predicting diffraction path loss using a 2-dimensional Digital Terrain Model (D.T.M.), the terrain profile is often simulated by a cascaded arrangement of canonical shapes as the perfectly absorbing half plane (or knife-edge), the wedge and the cylinder. It is often difficult to choose among all the diffraction models, that use these simple geometric shapes, the model that best suits to a given link. In this paper, an original algorithm, which makes an automatic choice of the suitable shape of a given diffracting obstacle, is described. This algorithm is then applied to CELAR (Centre d’Electronique de l’Armement) radio links at a frequency of 2.4 GHz.
