Radio wave propagation path loss in the irregular terrain environments

Abstract

This paper proposes an efficient, full-wave computation technique to investigate the radio wave propagation with irregular terrain environment, this methodology is based on the parabolic wave equation (PE). A split-step transform algorithm is used to solve the PE; a staircase terrain modeling is used to approximate complex terrain. It is used to calculate the reflection and interference mechanism in the standard atmosphere and successfully applied to model the field in the presence of knife edge and smoothness hill terrain. The results are validated by the comparisons with hybrid methods in AREPS.
