Alion produces Terrain Integrated Rough Earth Model (TIREM), a commercially available software tool that predicts radio frequency (RF) propagation loss over terrain and seawater for ground-based and airborne transmitters and receivers. STK/TIREM extends STK/Communications by enabling users to perform analyses along dynamic RF nodes for an overall system simulation. In addition to propagation loss over irregular terrain, STK/TIREM can also model near-field considerations, power density, and field strength equation.
