摘要
为了有效地估算先进红外传感器对隐身飞机的作用距离,以F-22与F-35进行对抗性仿真为想定,计算了F-22在长波和中波波段的红外辐射强度,拟合了典型条件下大气透过率的经验公式,推测了F-35机载IRST和AIM-9X红外导引头的特征参数,利用逐步逼近法,计算了F-35机载IRST和AIM-9X导弹导引头对F-22的作用距离。计算结果表明,F-22具有较强的红外隐身能力,可使F-35的IRST对其迎头作用距离不大于62 km,但是F-22在近距作战中,仍将受到红外格斗弹的较大威胁。鉴于F-22的红外辐射随红外传感器探测角度的变化而敏感性高的特点,建议飞机编队进行红外反隐身探测时,采用稀疏编队方式,以提高探测概率。
To compute the operating range of the advanced infrared detector for the stealth aircraft,the combat simulation scenario of F-22 and F-35 is given in the paper.In the scenario,the infrared radiation intensity of F-22 is computed in middle wave-band and long wave-band,the fitting formula of the atmospheric transmittance is given under typical conditions,the characteristic parameters of the F-35 airborne IRST and AIM-9X infrared seeker are inferred and the operating ranges of F-35 airborne IRST and AIM-9X infrared seeker for F-22 are computed with the gradually approaching method.The computation shows that F-22 has good stealth capability and the operating ranges of F-35 airborne IRST is less than 62 km from the nose of F-22 while the infrared dog-fight missiles threat F-22 in short range strikes.The infrared radiation of F-22 is sensitive to the detection angle of the infrared sensors,thus in the aircraft fleet anti-stealth infrared detection,sparse formation is adopted to increase the detection probability.
