ABSTRACT
The effect of the rotation of
a very good conducting cylinder on the backscattered field will be investigated
where the incident wave is considered as a plane wave in both polarizations (E-wave
and H-wave). Previous work has explained that rotation or vibration of the object
may induce phase changes of the scattered signal. Modulation during rotation or
vibration is referred to as micro-Doppler effect. Also, the effect of the rotation
of a conducting cylinder was investigated by many researchers in the past using
the Galilean transformation. These analyses conclude that the effect of rotation does not exist in the case of a perfectly conducting cylinder in
both polarizations. In this work, the Franklin
transformation is used instead of the Galilean transformation to analyze scattering
of both types of electromagnetic waves (H-wave and E-wave) by rotating a very good
circular conducting cylinder. This work shows that the scattered field is affected
by the rotation of a very good conducting cylinder, especially in the case of H-wave
(TE-mode). Finally, the model that will be presented is used to simulate rotation
using static backscattered field data of an arbitrary object.
