Abstract

Abstract

To the questions of Threat Assessment (TA), a technique for TA based on intuitionistic fuzzy reasoning is proposed. First, the major factors of effects of attacking targets from space or air on TA in joint air defense operations, nondeterminacy to TA, and the properties and vulnerabilities of the existing TA methods are analyzed. A model for TA measurement rank of threat degree is exposed. Then, the membership and nonmembership functions for input/output state variables are devised. The methods for quantification and measurement transformation to input variables in fuzzy strategy are addressed. The inference rules of the system are constructed with algorithms for reasoning and defuzzification devised. Subsequently, completeness and interactivity and consistency of rules contained in the rulebase are checked with a verification method to the rulebase presented. Finally, the validity is checked by providing TA instances with 20 typical targets.
