Cross-polarized target signature measurements

Cross-polarized laser scattering cross sections were measured for twenty-four different paint samples as a function of scattering angle at four visible krypton laser frequencies. The relative magnitudes of the measured cross sections at the four frequencies were used to define a multispectral signature vector for each paint sample. Measured data confirmed the theoretical prediction that the direction of the cross-polarized multispectral signature vector is independent of the scattering geometry.
