Description: The article is devoted the problem of recognition of air objects in the decision support systems. Descriptions of air objects for their recognition in the air surveillance system are considered. The list of signs of recognition for using the method of symmetric sums in the decision support systems is offered. The got estimation of probability of correct recognition for the example of test selection show expedience of realization of the developed approaches in decision support systems.
Keywords: recognition of air objects, method of symmetric sums
