Abstract :
This paper discusses texture analysis of high-resolution (<1-3 km) ocean microwave radiometric images (OMI). A large volume of spectral OMI was obtained with the use of a multi-channel polarimetric scanning microwave radiometer (PSR) in the fall 1997. During image processing it was found that texture of OMI can be represented by a multi-dimensional mosaic with variable brightness characteristics. A number of local small-scale geometrical objects (signatures) are observed in a large-scale mosaic image background. The authors suppose that these radiometric features may be associated with a spatial non-uniformity of the hydrophysical fields and their local instabilities
