Özet

Physical Optics formulation of electromagnetic scattering
by a perfect electric conductor (PEC) plate in arbitrary
motion in free space is provided. The investigation starts with
the derivation of equivalent electric moment of a Hertzian dipole
whose radiation pattern simulates the scattering pattern of the
PEC plate under arbitrary incidence. This dipole moment is
integrated into the radiation fields of an ideal Hertzian dipole
(with unit moment) in arbitrary motion to obtain the explicit
expressions of electric and magnetic fields scattered by a moving
PEC plate under arbitrary incidence. This is based on the method
of directional currents introduced recently by the present authors.
Doppler analysis of the signal received by a stationary observer
is carried out for certain modes of motion of the PEC plate.
Finally, time domain radar cross section of a plate in uniform
rectilinear motion is derived.
