Analysis of infrared radiation characteristics and detection technology of near-space hypersonic vehicles

Abstract

Hypersonic vehicles have a very complex trajectory and excellent maneuverability, which makes them effective in breaking the defence of enemy. Due to the strong and sustained infrared radiation emitted when they cruising rapidly in Near Space, researchers have paid attention to the infrared radiation characteristics of hypersonic targets and early warning detection mechanism. In order to acquire infrared radiation characteristics of hypersonic vehicles and collate research in infrared early warning detection technology phylogeny by the way, we have researched the Chinese and foreign progress of infrared radiation made by hypersonic target projectile, plume and the target entirety firstly; then the discussion of main method of infrared warning detection mechanism, technical models and conclusions as well. Lastly we discuss the main research directions in future by combining with the current research progress.
