This 46-page DIA reference report surveys detection and high-resolution tracking of atmospheric hypersonic vehicles through radar, infrared, optical, lidar, radio-reflection, acoustic, infrasound, and seismic signatures. It emphasizes shock waves, ionized wakes, hot surfaces, and turbulence, recommending wake databases and complementary sensing methods rather than claiming a single universal detector.
