In addition to the traditional re-entry warhead and re-entry capsule, more and more hypersonic objects appear in the near space in recent years, such as the X-51, X-37, and so on. Analysis of electromagnetic scattering properties of these objects has important values for identification, recognition, communication and control. Challenging problems to extract their scattering characteristics include...
An approximate approach to simulate the scattering by a rotating hypersonic object with plasma sheath is developed. Following geometric modeling, computational fluid dynamic tool is adopted to resolve the complex dielectric constant distribution of the plasma sheath. Then the Born approximate method is applied to evaluate the influences of the plasma sheath on the scattered field. Finally, Doppler...
