分析了高超声速飞行器(巡航导弹)的红外辐射特征.当巡航导弹飞行速度Ma>5时,其辐射峰值波长位于短波红外的波段范围,并且具有辐射功率大、随时间变化快等显著特征,最适于被短波红外传感器探测.说明了探测距离依赖于高超声速飞行器的红外辐射特征以及红外系统的性能参数.讨论了实现高超声速飞行器红外探测预警的思路和数学模型.
The characteristics of infrared radiation of hypersonic vehicles (cruise missiles) are analyzed.When the flight speed of cruise missile is Ma> 5, the peak wavelength of the radiation is in the band of shortwave infrared and has the prominent features of large radiation power and rapid change over time Which is suitable to be detected by shortwave infrared sensors.It is demonstrated that the detection distance depends on the characteristics of infrared radiation of hypersonic vehicles and the performance parameters of the infrared system.The ideas and mathematical models for realizing the early warning of hypersonic vehicle infrared detection are discussed.
