The aim of the work is to show how time-frequency representation by Wigner-Ville distribution of the echoes received by a synthetic aperture radar provides a useful tool for detection of moving objects and the estimation of the instantaneous phase shift induced by relative radar-object motion. The phase history is then used to compensate the received signal and to form a synthetic aperture with respect to the moving object, necessary to produce a high resolution image.
