Modelling of target acquisition within combat simulation and wargames
conference paper
This paper describes the target acquisition process from the perspective of modelling target acquisition as a part of modelling combat. Exchanging fire obviously is very important in combat. Conditions for direct fire are line-of-sight (LOS) and some kind of perception of the intended target. LOS is deterministic and can be calculated if there is a good digital representation of the terrain. But perception is considered a stochastic process with probabilities depending on the current situation. In most stochastic combat simulation programmes and wargames there is a module that models detection and perception. Because of tbe dynarnic character of combat situations for observing are changing rapidly. The models are calculating situations every x seconds (typical 5 - 30). Within such a timeframe occurrences of events and the effects of these events are calculated. Illustrative events are new observations. firings, etc. The target acquisition module is responsible for an actual list of observations. Each time-frame the list is updated: old observations are checked (observers or targets can be killed or moved) and new observations can be added. Because of the dynamic character only calculations are made for the coming time-frame For each observer and each potential target an observation probability is calculated and comparison with a random number determines if the considered observer/target will lead to a new observation. Input for this module are elements of the situation at hand and characteristics of observer (such as the sensor used) and target (such as its climensions). This paper addresses some of the limitations and problems of the current implementation of the target acquisition module.
