Remote sensing detection of complex oceanic features by using multi-parameter synthetic aperture radar (SAR)

The dynamic and random processes of ocean features and their multi-element mixs make the detections of ocean phenomena and information seperations so much complicated. The multi-parameter synthetic aperture radar (SAR), including multi-frequencies, multi-polarizations, multi-incident angles multi-resolutions and multi-swaths etc., are quite significant approaches in order to obtain a lot of oceanic multi-elements and the parameter estimations of these elementss according to SAR images. In the paper, the complication of the ocean processes and their application needs as well as multi-parameter SAR remote sensing abilities are briefly introduced at the first. The remote sensing principles and methodologies of multi-parameter SAR studying on complicated oceanic dynamic features are described. Multi-parameter SAR simulations and detections of sea surface waves, internal waves, currents and sea surface winds etc. are studied in detail. The further development of multi-parameter SAR systems and their potential in ocean applications is discussed and concluded at the final.
