A new method for fitting the return phase of a moving target in a curve which corresponds to its moving trajectory is proposed. This phase fitting method has no order limitation. It can be used in ISAR motion compensation either when the target moves uniformly rectilinearly or when the target moves non-uniformly rectilinearly.
