Studies of the location of azimuth modulation minima for Ku band ocean radar backscatter
An extensive data set of radar backscatter measurements at 14 GHz was used to evaluate the locations of the azimuthal modulation minima relative to the cross-wind directions. It was found that the minima were significantly offset from the cross-wind directions toward the downwind direction for the horizontal polarization data. These offsets were substantially smaller for the vertical polarization data. Simple scattering model calculations, based on the two-scale scattering approach, also show similar offsets. Implications of these results for the goephysical model function are discussed.
