摘要：本文件描述了地形综合粗糙地球模型(TIREM)和球面地球模型(SEM)的运行情况，包括模型所基于的工程公式。这两个模型都是模块化程序，具有许多符合ANSI Fortran标准的公共子例程。TIREM和SEM可分别用作粗糙土壤(已知地形剖面)或光滑土壤应用的独立传播模型。这两个模型都适当地考虑了自由空间扩展、反射、面波传播、绕射、对流层散射传播和大气吸收的影响。
Abstract : This document provides a description of the operation of the Terrain Integrated Rough Earth Model (TIREM) and the Spherical Earth Model (SEM), including the engineering formulations on which the models are based. Both models are modular programs with many common subroutines that conform with ANSI Fortran standards. TIREM and SEM can be used as independent propagation models for rough earth (with a known terrain profile) or smooth earth applications, respectively. Both models consider the effects of free space spreading, reflection, surface wave propagation, diffraction, tropospheric scatter propagation, and atmospheric absorption, as appropriate.
