Analysis of the returned signal model in bistatic radar systems

In this paper, taking the relativistic effect of high-velocity moving target into account, the Doppler shift, polarization deflection, reflection coefficient and phase delay of reflected electric field are analyzed rigorously under the assumptions that the incident signal to the target is a plane wave and the target is a perfect conductor plane. The analytic expressions are obtained. The present results are of practical significance to some extent for the accurate expression of the wideband returned signal of high-velocity moving target in bistatic radar system and understanding of wide-band ambiguity functions.
