Polarization signatures of targets compared with known signatures at known angles. Experiments demonstrated use of radar polarimetry to measure orientation of retroreflective target, even though target much smaller than resolution element of radar. Technique based on comparison of angular dependencies of measured and theoretically derived polarization signatures of target. Polarization signature also used to identify target. Tilt of reflector inferred by finding angle minimizing measure of difference between theoretical and measured radar cross sections of reflector.
