To the questions of battlefield situation assessment (BSA)

a technique for BSA based on intuitionistic fuzzy decision is proposed.First

BSA is concluded to an issue of synthetic judgement

and an intuitionistic fuzzy model for synthetic judgement is derived with a proof of the model normalized.Then

a system of evaluating goals for BSA is constructed

and approaches to effectiveness measures for evaluating goals and normalization of their values are described.Subsequently

methods of Delphi integrated with analytic hierarchy process (AHP) are exposed to be used for finding weight vectors of goals.Finally

the evaluating instances detailed in the course of joint operations of air defense get into investigation.The simulated results show that the technique can make sense of efficient synthetic assessment and comprehension to current battlefield situation with a higher dependability.
