Abstract:
In this paper we report on X- and L-band polarization coherence tomography in boreal forest structure mapping. We take advantage of HUTSCAT ranging scatterometer measurements and compare E-SAR derived vertical structure profiles with measured vertical scattering profiles. HUTSCAT measurements provide vertical scattering profile of the canopy and also provide supplemental forest height and ground phase estimates, allowing calculation of coherency profiles with alternative initial values. We present single baseline tomography for X-band and multibaseline tomography for L-band calculated with various initial values and compare the results with actual measurements of scattering profiles.
