New threat assessment non-parameter model in beyond-visual-range air combat

To cope with the shortage of current BVR(beyond-visual-range) air combat's non-parameters model. A new non-parameter model was formulated, which took into account the influence of fighter plane's air combat effectiveness, missile's attack-area, no-escape-area and radar's seek distance characteristic parameter and instantaneous geometry situation in air combat. Every superiority equation was formulated. The whole superiority index was calculated by the weighted linear method. The model illuminates BVR air combat well. Simulation result gives credit to the model.
