The infrared radiation of airplane targets and the radiation attenuation of the infrared radiation in the atmosphere were researched. Based on the existing theoretical study and the structure of the airplane, the infrared radiation sources of the airplane were divided into three categories: fuselage, hot spot and plume. Furthermore, calculation approaches to the character of infrared radiation for the three radiation sources at different wave band and different angle were proposed. According to infrared radiation transmittance in the atmosphere, a calculation method for the transmittance of atmosphere was put forward at different wave length and different target distance, and then this method was compared with Lowtran7. Finally, the radiant intensity received by the IR detector was computed after atmospheric attenuation at different wave band.
