Theoretical analysis of UHF propagation in a city street modeled as a random multislit waveguide

Abstract

In this work, we perform an analysis of a channel for UHF wave propagation in the city street. The street is modeled as a planar multislit waveguide with screens and slits distributed by a Poisson law. Statistical propagation characteristics in such a waveguide can be expressed in terms of multiple ray fields approaching the observer along a direct ray and the rays reflected by the waveguide walls. The corresponding average field and intensity distributions can be transformed into the sums of mode-like solutions using the Poisson summation formula. Numerical examples are presented and compared with the experimental data.
