Abstract
In combat simulations target classification and identification are very impor-
tant. In this research area several studies about simulating identification have
been done, most of them take a set of information like “the target is visually
identified hostile” to start the simulation with. Mostly classification is not taken
into account in identification problems.
In this report the input consists of basic sensor data and a priori knowl-
edge. This will be combined into information which is necessary to evaluate
the situation. Based on this information the complete situational awareness is
evaluated.
To derive information out of sensor data, facts have to be derived in three
areas, these are facts concerning position, identity and behaviour. Based on
these derived facts a decision will be made about the classification and the
identification of the target.
Two Bayesian reasoning models were designed for the decision processes of
the targets classification and identification. These models are designed as much
alike as possible. An implementation was made to test the models. In the
implementation temporal aspects are not taken into account but the results
were promising.
To conclude we conducted a literature survey to investigate the possibilities
of temporal reasoning in this project.
