Paper Abstract

Measurements made by the AirSAR polarimetric airborne system at longer wavelengths and for some vegetation types are inconsistent with a gaussian model for the data, and are much better described by a multivariate K distribution, although this does not appear adequate in all cases. Parameters suggested by the K distribution model are extracted from scattering matrix data for six different vegetation types at C, L and P bands and for four separate looks. As wavelength increases, spatial and inter-look variability increases markedly. The physical basis of this variability and its implications for data analysis are discussed.
