A Review of Studies on the Infrared Remote Sensing Characteristics of Hypersonic Cruise Vehicles

摘要

Hypersonic cruise vehicles emit intense infrared radiation when maneuvering at high speed in the near space, which highlights the practical significance of studying their infrared remote sensing characteristics. This paper makes a survey on the previous research into the infrared radiation characteristics of scramjet plumes, the infrared radiation characteristics of hypersonic cruise vehicle bodies and the infrared remote sensing characteristics of hypersonic cruise vehicles in the near space. Survey results show that, tentative studies have been carried out on infrared remote sensing technologies for hypersonic cruise vehicles, but more thorough and systematic research need to be conducted in depth. Further studies should focus on the infrared remote sensing mechanism of hypersonic cruise vehicles in the near space, and specific research is supposed to be targeted in particular to calculate the total infrared radiation intensity, with not only the infrared radiation of scramjet plumes and vehicle bodies taken into account, but also atmospheric attenuation and background radiation into consideration.
