Abstract :
The statistical characteristics and the orientation of a remotely generated swell superimposed upon a local wind generated rough sea surface are determined from polarimetric data. The full wave approach is used to determine the incoherent backscatter Mueller matrix elements and the incoherent backscatter Graves power matrix elements as functions of azimuth and elevation angles, and rough sea surface (with swell) parameters. Using the optimal backscatter angle and polarization of the incident and scattered fields, the ability to reliably determine the orientation and statistical characteristics of remotely generated swells is enhanced.
