TACTICAL MISSION ANALYSIS METHODOLOGY

The Tactical Mission Analysis Station (TMAS) is a graphics-oriented, interactive computer model designed for use on Silicon Graphics engineering workstations. TMAS was developed to satisfy the needs of analysts in the survivability and human factors communities by allowing quick, interactive creation of missions that take place in a nap-of-the-earth combat environment. TMAS models the fundamental elements of a combat mission, including terrain, performance of rotorcraft and fixed-wing aircraft, and the capabilities of friendly and threat weapon systems. Terrain and feature information is generated from Defense Mapping Agency Digital Terrain Elevation Data and Digital Feature Analysis Data. Weapon, sensor, and air vehicle performance parameters are stored in data files, allowing the model itself to remain unclassified. This feature allows easy substitution of alternate parameter sets when conducting tradeoff studies and sensitivity analyses. Simulation data are stored in a flight data recorder for use in post-mission analysis and display functions.
