Given a polarimetric image, this module synthesizes the radar
image for any specified transmit and receive polarization combination.
Angles are specified by the user for both the Rotation angle (ψ)
and the Ellipticity angle (χ) for both the
transmit and recieve antennas.
The Ellipticity angle ranges from -45o
(right circular polarization) to 0o
(linear polarization) to +45o
(left circular polarization),
while the Rotation angle ranges from -90o
(vertical polarization) to +90o
