N2 - Autofocusing of SAR images is addressed using a polynomial model for the instantaneous phase shift induced by the relative radar/scene motion. The resulting method is capable of discriminating moving target echoes from the stationary background by exploiting the different phase modulation due to the different motion laws. The algorithm is applied to real SAR images and to computer-generated images obtained by superimposing a simulated echo from a pointlike moving target to a real SAR image.
