The application of pattern recognition to missile detection and decoy discrimination was investigated. As a result of these investigations, a mathematical theory was developed to achieve the optimum combination of measurable or computable target properties to achieve the separation of target types, based on their observable properties. The input to the theory is the set of discrimination techniques and useful target-signature parameters. The theory operates on these inputs to determine their optimum method of combination and thus determine what the essential properties of targets are that allow their recognition. An important attribute of the theory is that it does not become obsolete as new techniques are developed and breakthroughs are achieved in methods of distinguishing one type of target or threat from another. The achievement of the present theory is that it states how techniques developed by others are to be combined.
