Abstract : according to the probability model of aerointerceptor ' s interception effect under optimum target distribution form ( tdf ), the optimum tdf in which aerointerceptors intercept groups of attack - planes are deduced, the relation among dispatching fighter number, airport ' s tactical and technological parameters, aerointerceptor ' s tactical and technological parameters, and attack - situation of attack - planes is researched, the quantitacation relationship are then determined which should satisfy when airport ' s aerointerceptors conduct optimum target distribution on groups of attack - planes. starting from operational practice, the model can provide certain theoretical basis for the military decisions
文摘:根據截擊機在優化的目標分配形式下攔截效果的概率模型，導出了截擊機在攔截多攻擊機機群時的最優目標分配形式;研究了機場飛機起飛架數與機場戰術、技術參數、機場飛機的戰術、技術參數以及與攻擊機的進攻態勢之間的關系;確定了多機場飛機對多攻擊機機群進行最優目標分配時所應滿足的量化關系，給出的模型可對作戰決策過程提供理論依據。 -
