The FORTRAN program TERRAIN is a deterministic model of a tactical aircraft penetrating a Surface-to-Air (SAM) and Anti-Aircraft Artillery (AAA) threat. TERRAIN generates a terrain following flight path profile based on specified flight parameters and then assesses the aircraft vulnerability in terms of exposure time and shots taken by individual threat site and the total defense. Modifications were made to assess aircraft survivability (the probability of kill of the aircraft) and to calculate the effect on the probability of kill of electronic countermeasures. The TERRAIN model is particularly sensitive to the selection of beddown, rate of fire for AAA, aircraft velocity, and aircraft commanded clearance altitude. A comparison of the strengths and weaknesses of the original TERRAIN model, the modified TERRAIN model, and six other SAM/AAA models has been compiled. A user's guide for the modified TERRAIN model is provided. (Author)
