An unsupervised classification method of flight states for …
WEBMay 1, 2023 · However, the classification of hypersonic vehicles is different from the pixel classification in HSIs, which has only HFs available. In response to these shortcomings, in this paper, we propose an unsupervised classification algorithm with high classification accuracy based on clustering to classify the HFs of flight states of hypersonic targets.
WEBAn important range of hypersonic speeds extends from Mach 20 to 25 and includes the velocities of long-range ballistic missiles and of satellites re-entering from orbit.
