Abstract :
A novel passive microwave-imaging methodology is developed to be used in ocean remote sensing. This technique is based on high-resolution scanning radiometric observations and digital image analysis. Two-dimensional, ocean thermal microwave emission features (signatures) are detected in the form of extended texture mosaics and distinct objects. Usually they are revealed as sets of low-contrast cold and hot spots. We hypothesize that the observed signatures can be associated with local oceanic phenomena and hydrodynamical disturbances. Several basic examples are presented and explained.
