    %% Copolarization Signature of Dihedral for Left and Right Circular Polarizations
% This example shows how to obtain numerical values for the
% polarization signatures of a dihedral target for left and right
% circular polarized incident waves.

% Specify the radar cross-section matrix of a dihedral

%%
% Specify a left circularly polarized wave and obtain its tilt angle
% and ellipticity.
fv = 1/sqrt(2)*[1;1i];
[tilt_lcp,el_lcp] = polellip(fv);

% Specify a right circularly polarized wave by complex conjugation
% of a left circulary polarized wave. Obtain its tilt angle and
% ellipticity.

% Both tilt angles are 45 degrees. Compute the copolarization
% and cross-polarization signatures for the two waves.
