%% 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. % Copyright 2015 The MathWorks, Inc. %% % Specify the radar cross-section matrix of a dihedral rscmat = [-1,0;0,1]; %% % 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); disp([tilt_lcp,el_lcp]) %% % Specify a right circularly polarized wave by complex conjugation % of a left circulary polarized wave. Obtain its tilt angle and % ellipticity. [tilt_rcp,el_rcp] = polellip(conj(fv)); disp([tilt_rcp,el_rcp]) %% % Both tilt angles are 45 degrees. Compute the copolarization % and cross-polarization signatures for the two waves. el = [el_lcp, el_rcp]; tilt = tilt_rcp; respc = polsignature(rscmat,'c',el,tilt); respx = polsignature(rscmat,'x',el,tilt); disp(respc) disp(respx)
