摘要: 根据红外探测器作用距离方程,综合大气传输透过率计算方法、临界辐射强度计算方法和发现概率计算方法,建立了飞行器红外探测概率及暴露距离仿真计算方法。分析了暴露距离概念的物理意义;建立了红外探测计算仿真系统。对一架具有已知红外辐射强度分布、以一定路线飞行的飞行器,可以计算其对红外探测器的隐身性能,包括探测概率曲线和暴露距离曲线。初步建立了飞行器红外隐身评估方法,为飞行器的红外隐身性能评估和红外隐身设计提供了重要手段。

Abstract: According to the infrared-detector operating range equation, the method used to simulate the infrared detection probability and exposure of an aircraft was established, with the use of atmospheric transmission rate calculation method, the critical radiation strength calculation method and the detection probability calculation method. The physical meaning of the exposed range was analyzed, and an infrared detection simulation system was established. The system could be used to assess the infrared stealth performance of an aircraft, which includes the curve of detection probability and the curve of exposed range, giving the flight route and the infrared radiation intensity distribution of the aircraft. A preliminary method used to assess the infrared stealth performance was established. This method could provide an important tool to the aircraft infrared stealth design.

Key words: exposed range, detection probability, penetration simulation, infrared stealth
