Analysis of Infrared Satellite′s Detectability for Common Hypersonic Glide Body
With the rapid development of near-space hypersonic technology and the use of near-space hypersonic missiles, new military threats have become a reality. Due to the low flight trajectory of the near-space hypersonic missile and the characteristics of maneuvering flight, it is possible to predict its flight trajectory only by real-time detection and tracking. Affected by the curvature of the earth and other factors, the detection range of ground-based radar system for near-space hypersonic missile is limited, and there is a huge demand for the number of radars for networking detection, so satellite detection is a better means. The infrared radiation characteristics of the U.S. Navy and Army′s common hypersonic glide body (C-HGB) are analyzed preliminarily. Combined with the detection capabilities of the high-orbit infrared early warning satellite, the detectability of the early warning satellites to the C-HGB in the gliding flight stage is analyzed preliminarily. The results show that the current high-orbit infrared early warning satellites are difficult to detect C-HGB in the gliding phase, so it is necessary to improve the satellite infrared detection system or build a low-orbit satellite constellation.
