Abstract:

The visual aquisition of militarily significant objects in a natural terrain environment has, in the past two decades come to the forefront as a major consideration in the design of future military weapon systems. With the surge in sophistication of military hardware design, there is still a strong reliance on the capabilities of the human observer to successfully locate, identify, and bring fire upon enemy elements before he himself, is destroyed. This location of the enemy threat is most often accomplished without the assistance of any clues or devices other than the appearance of an object in the terrain. Military planners now rely heavily on computer-simulated war games to evaluate the desirability and investigate tactics and employment of proposed weapon systems in a combat environment. Other questions which might be asked are how certain changes in a system affect performance in combat. However, construction of sophisticated computer-simulation techniques has outpaced the development of models adequately describing the capabilities of the human visual system to locate and identify the enemy. In this thesis, models of the visual detection of stationary and moving targets in a natural terrain setting are developed, with emphasis toward their implementation in a combat simulation.
