Abstract :
Discusses interpretations of polarization synthesis results of simple point targets and distributed scatterers such as vegetation. Polarization responses are displayed on both Poincare sphere and Cartesian space. Polarization responses of dihedral target and vegetation media are compared to identify the dominant scattering mechanism. Measurements of co-polarized backscatter phase measurements are used to show that the tilt angle in polarization response plot is due to backscatter phase difference
