Multi-frequency polarimetric SAR interferometry for vegetation structure extraction

The authors compare the relative information content of single baseline polarimetric interferometry at C-, L- and P-bands and conclude as to the best frequency range for vegetation structure estimation. They present an inversion algorithm for vegetated terrain based on a coherent polarimetric scattering model of volume and surface scattering. They point out some general aspects of using multi-frequency interferometric techniques for vegetation studies and use L- and P-band data from the DLR E-SAR system to verify the theoretical models.
