摘要：

When a near space hypersonic vehicle (NHV) reenters the atmosphere, its scattering characteristics would be significantly changed by the formation of plasma sheath and wake. In this paper, the scattering characteristics of typical hypersonic near space vehicle are studied. Main contents included the RCS simulating of hypersonic vehicle surrounded by plasma sheath, underdense turbulent wake and laminar wake. The results show that the RCS of hypersonic near space vehicle would be decreased by plasma sheath in the back scattering direction. The RCS of hypersonic near space vehicle would be increased by the underdense turbulent wake at low frequency. But with the increase of radar frequency, the effect of underdense turbulent wake would be unobvious. Finally, Low frequency radar and bistatic radar are suggested to detect hypersonic near space vehicle.
