Patent ID: 8924325

Claim:
A system for evaluating the threat posed by sensed targets and for taking countermeasures against certain threats, said system comprising: at least one memory device for storing predetermined threat hypotheses and doctrinal information representing the nature of a particular type of threat, and a risk tolerance attributed to that particular type of threat, beyond which countermeasures are taken against said threat according to said doctrinal information; a Choquet threat discernment processor, the threat discernment processor responsive to said threat hypotheses and doctrinal information stored on the at least one memory device, and configured to execute instructions for performing the step of: identifying a threat level represented by each sensed target; a threshold arrangement for evaluating the threat level; and countermeasures responsive to said threshold arrangement for engaging those targets in which the threat levels lie above the threshold, wherein said Choquet threat discernment processor: a) determines certainty values representing an accuracy level of the target data for a sensed target as sensed by a given sensor; b) determines individual importance value weights, one for each of said predetermined threat hypotheses, each said importance value weight of the sensed target data having a value representing the degree of correlation of the sensed target data with a given one of said predetermined threat hypotheses; c) determines Certainty Equivalent (CE) values for each set of threat hypotheses based on Choquet statistical processing of mean and variance for said given individual importance value weights for a given set of certainty values of the sensed target data and the risk tolerance attributed to that particular type of threat from said doctrinal information, wherein each threat hypothesis has a corresponding CE value corresponding to the calculated threat level of the sensed target.
