基于机会约束规划的空空导弹期望值广义攻击区

Expected Generalization Attack Area of Air-to-air Missile Based on Chance-constrained Programming

针对传统火控攻击方式在电子干扰环境下超视距攻击能力降低的问题,提出了利用无源侦察系统获取的带有误差的目标信息进行火控计算的空空导弹广义攻击区的概念。采用机会约束规划方法建立了期望值广义攻击区的数学模型,给出了基于蒙特卡罗模拟的计算方法。仿真结果表明,采用期望值广义攻击区可以增加电子干扰环境下空空导弹的发射机会。根据指定不同期望命中概率而得到的广义攻击区等概率曲线,飞行员可以提高在复杂战场环境下攻击作战的灵活性。

Aiming at the reduction of beyond-vision-range attack ability of traditional fire attack mode under electronic jamming environment,the concept of generalized attack area（GAA） of air- to-air missile（AAM） was proposed, which was calculated with the imprecise target information acquired by the passive reconnaissance system. The model of the expected GAA was established by adopting chance-constrained programming, and the compution method based on Monte Carlo simulation was given. The simulation result shows that the launch opportunity of AAM under electronic jamming environment is increased with the expected AAM. According to the equiprobability curve of GAA with different expected hit probability, the operational flexibility under the complex battlefield environment can be improved.
