Abstract
Advanced satellite SAR systems, such as Cosmo SkyMed, provide high resolution images with reasonably short revisiting time, allowing for a number of applications in areas such as Homeland Security and Maritime Surveillance. Especially in the case of maritime surveillance, non-ccoperative moving targets imaging represent a challenge for SAR systems as the complex target motions produce evident image defocusing. In the present paper, we show evidence of the effectiveness of the applications of ISAR processing to obtain well focused images of such type of targets. It will be also shown that super-resolution techniques are applicable to targets affected by complex motions after ISAR processing is used. © 2012 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
