Characterization of Coherent Scatterers in Natural Terrain Using SAR Polarimetry
Abstract
In this paper, we present results from detection of coherent scatterers in nonurban areas, using polarimetric SAR data from the airborne EMISAR and the spaceborne ALOS PALSAR instrument. By applying a signal-to- clutter ratio test for coherent point targets, we show that by using polarimetric information in the Pauli decomposition, we increase the number of detected targets by a factor of two compared to using only a single polarization. A preliminary classification into elementary scattering mechanisms using the Cameron symmetric scatterer decomposition is also reported.
