The Comparative Study of Two-color Infrared Detection

The infrared baits which the airplane uses in view of the current air fight are getting more and more,and the current infrared air-to-air missile's detection wave band is relatively narrow.To improve air-to-air missile's detectivity and recognition capability,the viewpoint of multi-wave band dual-color detection and recognition is proposed.In the paper the energy distribution of aircraft engines caudal flame,aircraft skin and infrared decoy in different bands are analyzed,by using Planck's Law and Wien's Displacement Law.The stimulation of dual color integral ratio in the midwave/long wave,the shortwave/midwave,the shortwave/long wave bands are carried out.The method of multi-wave band dual-color detection is put forward based on the analysis and simulation results.
