  I investigate the effects of movement on radar cross section calculations.
The results show that relativistic effects (the constant velocity case) can
change the RCS of moving targets by changing the incident plane wave field
vectors. As in the Doppler effect, the changes in the fields are proportional
to $\frac{v}{c}$. For accelerated objects, using the Newtonian equations of
motion yields an effective electric field (or effective current density) on the
object due to the finite mass of the conducting electrons. The results indicate
that the magnetic moment of an accelerated object is different from that of an
un-accelerated object, and this difference can change the RCS of the object.
Results for moving sphere and non-uniformly rotating sphere are given and
compared with static (\textbf{v}=0) case.
