The Double Bounce scattering mechanism is usually compared to the ideal polarimetric response of a metallic dihedral reflector, for instance in the Pauli basis. This is however only valid for perfect metallic targets, perfectly aligned with the sensor. When rotated, the double bounce mechanism gives both a double bounce electromagnetic response (VV and HH) and a crosspolarization response. This paper focuses on this and illustrates its use.
