Analysis of infrared radiation characteristics and low-altitude detectability of a foreign stealth aircraft
摘要
Abstract
Taking a certain type of foreign stealth aircraft as the analysis object,and by establishing infrared spectral radiation models,Bidirectional Reflectance Distribution Function(BRDF)model and atmospheric absorp-tion/scattering models for different parts of the aircraft,the paper calculates and obtains the spatial radiation ener-gy distribution of the aircraft under several typical solar incidence angles,observation angles and flight attitude in mid-latitude summer of the northern hemisphere.On this basis,the low altitude detection model and detection sce-nario are established,and the detection capability of a foreign equipped airborne infrared search and tracking sys-tem(IRST)to the stealth aircraft is analyzed.The research results are shown as follows:Afterburning state,atmo-spheric conditions,solar incidence angles,skin reflectance,detection band and observation angles all affect the in-frared radiation characteristics and detectability of the aircraft.In the low-altitude detection mode,the effect of so-lar reflection is relatively limited,and the radiation intensity is mainly affected by the afterburning state and detec-tion band,showing significant diversity and difference in spatial distribution.关键词
