Study of Infrared Signatures of Aircraft
飞机红外特征研究

The aircraft stealth technology is developed correspondingly with the development of infrared imaging detection and tracking technologies. To let an aircraft be stealth, the infrared signatures of it should be analyzed. The main factors which have influence on infrared radiation characteristics are analyzed. On the basis of the traditional calculation methods, a method for calculating the infrared radiation from the exhaust gas, nozzle and skin of an aircraft and the solar radiation reflected from the aircraft skin is given. The calculation result shows that the calculation method is practical and reliable and can meet the requirements of engineering calculation and practical application.
