Abstract:

Modeling air defense threat is an important basis of tactical mission rehearsal. Adopting the thought of artificial potential field, potential function is constructed for describing the effects of air defense threat on unmanned air vehicle (UAV) mission completion. The combat capacity index of air defense threat is computed by using the theory of fuzzy multiattribute decision. The counterwork capacity index of UAV to air defense threat is quantized according to jam measures, maneuverability, speed and flight height. The pessimism rule is used when the information is with uncertainty. The model is with the sum form of functions which are differentiable. Simulation results show that the computation is simple and takes only a few memories. The air defense threat potential field model is able to describe the combat capacity, the time, space characteristics of air defense threat and the counterwork capacity of UAV.
