Study on Ship Imaging Using SAR Real Data

Ship ISAR imaging is studied in the paper based on the airborne SAR real data. SAR imaging deals with static targets. A moving ship appears blurred in the SAR image. For the purpose of getting high resolution ship images, ISAR imagery may be introduced into the imaging due to the non-cooperative character of the ship target. In the paper, the extraction of ship data from SAR real data is described firstly. Then, effective ISAR motion compensation methods appropriate to ship imaging are discussed. Finally, clear images of several typical ships are presented. This work provides effective processing methods for ship imaging when the airborne radar works in SAR mode.
