攻击直升机是现代战争中最具威胁的作战兵器之一,作战模拟对于武器系统作战效能分析具有不可替代的作用。本文用马尔柯夫过程建立了直升机在威胁环境中攻击一个地面目标的数学模型,导出了攻击任务成功率、目标被击毁率和直生机损失率等效能的表达式和计算方法,讨论了攻击直升机的费用-效能关系、最优战斗时间以及通过计算实例说明改装机载电子对抗设备对作战效能的影响 Attack helicopters are one of the most threatening combat weapons in modern warfare. Combat simulation plays an irreplaceable role in the combat effectiveness analysis of weapon systems. In this paper, a mathematical model of a helicopter attacking a ground target in a threatening environment is established by using the Markov process. The expressions and calculation methods of attack mission success rate, target destruction rate and loss of straight machine probability are derived. Attack helicopters Cost-Effectiveness Relationship, Optimal Fighting Time, and Calculation Example to Illustrate the Impact of Modified Airborne Electronic Countermeasure Equipment on Operational Effectiveness
