摘要:
复杂红外对抗环境已成为空中作战的主要场景,而空中红外对抗过程本质上具有高度随机性,必然对红外空空导弹制导精度产生显著影响。本文在分析空中红外对抗随机过程的基础上,基于排队论模型构建了平稳状态下红外诱饵平均被识别时间及其制导扰动的计算模型,并采用高阶伴随分析方法建立了全弹道制导精度的影响分析模型,形成了涵盖从红外诱饵投放、识别、制导扰动直至最终脱靶量计算的空中对抗全程制导精度分析方法。通过对典型对抗过程的实例仿真计算,验证了本文方法能够有效分析干扰对抗模式与导弹制导系统主要参数对导弹最终脱靶量作用影响的内在机理与数值关系,揭示了影响制导系统空中对抗性能的一般规律,为红外空空导弹抗干扰能力的设计改进提供了有效支撑。
Abstract:
The infrared countermeasure (IRCM) scenario has become the top issue in modern air combat because it is highly random and vitally affects IR air-to-air missile (AAM) guidance precision. This paper presents an analysis of the interacting stochastic procedure between an incoming missile and successively launched decoys. First, a disturbance calculation model that focuses on the guidance problem for a single decoy is proposed. Next, the steady state solution of the airborne IRCM interacting stochastic procedure is obtained using queuing theory, and this solution provides the average decoy-launching interval and discrimination time as inputs to the disturbance model. Furthermore, a high-order adjoint method is used to analyze the miss distance. Finally, the internal mechanism of the IR AAM guidance performance against the IRCM interaction is calculated and analyzed completely. The results obtained from this analysis provided insights on both guidance precision analysis and future system evolution for improving the counter infrared countermeasure (CIRCM) capability.
