红外成像导弹目标截获概率

Target acquisition probability of infrared imaging missile

导弹截获目标的概率是红外成像导弹的一项重要的设计指标。传统的目标截获概率通常通过统计方法得到,该方法需要建立导弹制导控制系统的详细数学模型,因此不适合在导弹总体方案设计阶段使用。针对传统方法的缺陷,通过分析影响红外成像导弹截获概率的主要误差源,从而建立了截获概率的数学模型,从理论分析角度给出了导弹截获概率的计算方法。仿真结果表明,建立的截获概率数学模型正确可信,计算的目标截获概率与传统统计方法结果相当,可以辅助进行各项误差的精度分配以及系统指标的设计,具有重要的理论意义和实际应用价值。

The target acquisition probability is a key design parameter for the infrared imaging missile.The traditional target acquisition probability calculation method depends on the statistical theory which requires a detailed mathematical model of the missile guidance and control system,so it is not suitable for the stage of missile overall design.According to these disadvantages,on the basis of analyzing the main error sources who affect the calculation of missile target acquisition probability,a mathematical model of target acquisition probability was designed;through this model,we can get the missile target acquisition probability at the stage of missile overall design.A comparative simulation was made between the calculation method in this paper and the traditional statistical method.The simulation results show that the calculation method is correct and credible,and can help missile designers to complete the precision distribution of those error sources and the design of system index,which is of important theoretical significance and practical value.
