Terrain Parabolic Equation Model (TPEM). Version 1.5. User's Manual.

Abstract

This document describes the Terrain Parabolic Equation Model (TPEM) Version 1.5, its operation, and the format required for the environmental and system input files. TPEM 1.5 calculates and plots propagation loss in dB on a height vs. range display. It allows for range-dependent refractivity environments and variable terrain. TPEM 1.5 is based on methods and source code originally developed by Fred Tappert, from the University of Miami, for propagation over a smooth surface. It is a pure PE model based on the split-step Fourier method.
