Polarization-Modulation Method of Measuring Bearing and Roll Angles of a Moving Object from Orthogonally Elliptically Polarized Signals of a Radio Beacon

The method of modulation polarimetry used for measuring bearing and roll angles of a moving object (MO) is investigated for the general case of a radio beacon transmitting orthogonally elliptically polarized signals from two spatially spaced points. Resultant vector signals of the radio beacon are received by the antenna of an onboard single-channel radio receiving device in the path of which a polarization modulator is inserted. The bearing and roll angles are estimated at the output from the receiver at the frequency multiple to the frequency of polarization modulation of the resultant signals received by the radio beacon.
