Abstract :
Non-cooperative moving targets appear defocussed within SAR images. Moreover, in the case of ground targets, the blurring effect due to the uncompensated target motion decreases detection capabilities. In this work, clutter suppression by means of Space Doppler Adaptive Processing and ISAR imaging are combined to obtain high resolution images of non-cooperative moving targets within SAR images. Results obtained by processing a real dataset prove the effectiveness of the proposed processing chain.
