Abstract :
The validity of the product model and the corresponding K distribution for high resolution images is studied. Of particular interest are the order parameter for several types of clutter and its relation to the polarization. In experimental tests, low order parameters are measured for most clutter, indicating the high resolution enhances the texture effect. Also an extension of the product model considering backscattering from multiple layers is presented, in order to explain polarimetric variation in the measured order parameters for the forest areas at L-band
