An expert system of air attack target recognition model based on blackboard model is built after the target information is synthesized, it can simulate the recognition thought of the domain experts.

Focused on the characteristics of air-target, a method of air-attack targets threat evaluation is presented according to the theory and method of fuzzy multi-objective decision making (MODM).

The hierarchy of an aerial attack target menace evaluation model in air defense system is established using the hierachy analysis method, and the cost weighting coefficient is obtained.
