Spatial anisotropy assessment of the forest vegetation heterogeneity at various azimuth angles of the radar polarimetric sensing
The results of studies to assess the texture of L- and C-band radar polarimetric images obtained from SIR-C and ALOS PALSAR-1 satellites for the analysis of forest vegetation characteristics using different signatures are summarized. A fractal polarization signature is proposed for the study, which allows to estimate the spatial anisotropy of forest vegetation inhomogeneities at different azimuthal angles of radar sensing. In addition, the signature of lacunarity is suggested as a tool for qualitative evaluation of the angular distribution of tree branches. The heterogeneities of forest vegetation at the test site near the Baikal Lake have been estimated based on the results of the analysis of fractal dimension and lacunarity at different states of the polarization ellipse.
