Abstract
A theory of the displaced phase center antenna system for space based radar applications is presented. The matching condition required to compensate for the motion of the satellite platform so that clutter cancellation can be achieved is first derived. Analytical expressions for the signal and clutter covariance matrices are given. With the aid of a simplified model, numerical values of an improvement factor are obtained. These results illustrate the dependence of the level of clutter rejection on radar parameters such as: grazing angle, pulse train duration, pulse repetition rate and antenna aperture size.
