1. A method for reducing clutter in synthetic aperture radar (SAR) images of the ocean surface, the method comprising the steps of:

  • obtaining spotlight mode SAR images of a selected patch of the ocean surface;

    computing an estimate of the ocean surface parameters of the patch of the ocean surface as it was at the time that the spotlight mode SAR images were obtained; and

    modifying the spotlight mode SAR images, based on the ocean surface parameters, to remove distortion effects caused by movements in the ocean surface, and to produce clutter-reduced SAR images.
