Abstract
Analyzed the radiation intensity of the influence factors on infrared radiation characteristics of missiles, such as sun, clouds, atmosphere, Earth's surface of desert, and the dust. Then, the influence of desert sandy material composition and dust environment, which can work in the infrared radiation characteristics of Earth's surface, are studied emphatically. After that, the infrared radiation calculation models of the missile's skin, exhaust nuzzle, and wake flame are built, and analyzed the infrared radiation intensity changes with detection angles through different detection distances. At last, got the conclusion, wake flame is the first main source of missile's infrared radiation, which focus on the bands between 3~5μm, infrared radiation of the skin is mainly between 8~12 μm, with the increase of detection distance, the attenuation of missile's infrared radiation also increased.关键词
