A comprehensive threat assessment method for group aircrafts cooperative air defensive combat under command of AWACS

Threat assessment is the precondition of target assignment for an airborne warning and control system(AWACS). But the existing threat assessment methods in group aircrafts cooperative air defensive combat under command of AWACS, as occasionally found in the open literature, are, in our opinion, not satisfactory and can be much improved. We present a new method which is based on hybrid multi-attribute decision-making when the information about attribute weights is completely unknown. For dealing with qualitative information and quantitative data at the same time, we turn fuzzy numbers into precise numbers. A model with adjustability is proposed to seek the objective weight based on entropy and then the subjective weight and objective weight are linearly integrated into the general weight. Finally, the results of simulation and sensitivity analysis for an example show that using the above method in threat assessment of AWACS is feasible.
