The invention provides an unmanned platform air opposition deduction method and an apparatus. The method comprises the following steps of 101, acquiring state vectors of a first unmanned platform anda second unmanned platform currently; 102, according to the state vectors, determining whether the two unmanned platforms satisfy an emission requirement, if the two unmanned platforms do not satisfythe emission requirement, according to a preset maneuver action decision making method, calculating optimal maneuver actions of the two unmanned platforms respectively and going to step103; if the twounmanned platforms satisfy the emission requirement, emitting missiles by the corresponding unmanned platform, and going to step104, wherein the number of the missiles is reduced; 103, according to amaneuver action coding method, generating a first instruction and a second instruction for the optimal maneuver actions of the two unmanned platforms, sending to the corresponding unmanned platform,and returning to the step101; and 104, according to a termination condition determination method, determining a deduction process, if the deduction process satisfies the condition, determining that unmanned platform air opposition deduction is ended, otherwise, returning to the step101. In the invention, through multiple groups of simulation experiment data, an unmanned platform intelligent decision algorithm is evaluated.
