作战飞机的空-地攻击效能评估

ASSESSMENTS OF AIR TO SURFACE TARGET ATTACKING EFFECTIVENESS FOR A COMBAT AIRCRAFT

用概率方法建立了描述单一飞机在威胁环境中攻击一个地面被动目标的数学模型，导出飞机对地攻击作战的任务成功率、目标被击毁率和飞机损失率等效能的表达式，给出用于效能评估的有关事件发生概率的计算公式，通过计算实例讨论了作战飞机空－地攻击效能的各种度量。

By using a probabilistic method, a mathematical model was established to describe a single aircraft attacking a single passive surface target in a threat environment. The expressions of the probability of mission success, the probability that the target is killed and the probability that the aircraft is killed for an air to surface target attacking operation were then deduced. The formulae for calculating the probability that the aircraft is killed once it encounters an enemy threat, the frequency that the aircraft encounters enemy threat, the probability that the target is killed once attacked by the aircraft and the mean time that the aircraft takes to acquire and attack the target are presented. Finally, various effectiveness measures of a combat aircraft in an air to surface attacking mission were discussed with a practical example.
