High Grazing Angle and High Resolution Sea Clutter: Correlation and Polarisation Analyses

Abstract

Spatial and temporal correlations of high grazing angle high resolution sea clutter collected by the DSTO Ingara polarimetric X-band system are studied. It seems that wavelengths of wind waves and swells are retrievable from the range correlation whereas the periods of the waves and swells are recoverable from the azimuthal correlation. The polarimetric behavior of sea clutter is also studied, and it is found that the Bragg scattering is the dominant scattering mechanism of the sea clutter. Quantitative analysis indicates that the best polarization in terms of detecting small targets on the sea surface include double bounce, cross-slant-45- degree, RR and HH polarizations.
