Measurement of Ocean Spatial Coherence by Spaceborne Synthetic Aperture Radar

Abstract

The long term goal of this work is specify long ocean wave spatial coherence in a way that is useful for designers of Mobile Offshore Bases (MOBs). The proposed sizes of MOBs are on the order of a kilometer or more and pose unique design challenges. In particular, we intend to generate a statistical database of wave "long-crestedness" and "groupiness" from spaceborne synthetic aperture radar (SAR) imagery of the ocean surface. We will place emphasis on those SAR images in high sea states, the environmental conditions that will pose the greatest challenge to MOBs. SAR images from hurricanes will likely prove the most useful.
