In order to study the space-based infrared remote sensing characteristics of hypersonic vehicles, this paper takes the simplified projectile model of HIFIRE-1 aircraft as the object to carry out simulation research. Firstly, the infrared radiation calculation model of the target projectile is established, including the aerodynamic thermal effect engineering simulation model, the projectile temperature calculation model and the projectile infrared radiation calculation model; Secondly, the space-based infrared detection model of hypersonic targets by calculating the spectral contrast between the target and the background is established; Finally, space-based infrared remote sensing characteristics of high orbit infrared early warning satellite for hypersonic vehicles under typical conditions are simulated and analyzed. The results show that, when the hypersonic vehicles fly at a speed of 6Ma at 25km, the detection ability of high orbit infrared early warning satellite for hypersonic target projectile is weak.
