Identification of the property of a moving medium by the reflected electromagnetic wave

The method of obtaining the information about the properties of a moving medium by the electromagnetic wave reflected from it has been derived. Based on this method, one can identify the moving medium to be a dielectric medium, a perfect conductor, or plasma, and even determine the dielectric constants of dielectric moving media, or the magnitude of n
p
and hence the electron density of a plasma from the polarization state and the magnitude of the reflected field vectors.
