Enhanced Procedure for Double Knife-Edge Diffraction Path-Loss Assessment

Deygout method still remains one of the most frequently used approximate methods for path-loss assessment, but generally, yields overestimated loss in most cases. This is especially obvious when two obstacles stand relatively close to each other with relatively equal heights. In this paper we propose a method to eliminate this deviation. In that aim, several combinations of double diffraction scenarios are presented in order to compare our results with Deygout’s, taking the Vogler’s numerical results as a reference.
