Abstract

There are investigated amplitude-phase method of the moving object bearing when there are used orthogonal linear polarized radio signals illuminated simultaneously from two horizontally spaced points with known co-ordinates. The bearing is measured onboard the moving object with two canal UHF system utilizing the amplitude-phase processing of the signals received within the linear polarization basis. The analysis is carried out for the general case when the orts of the linear polarization basis in which the measurements are made are oriented at a certain angle to the measurement plane.
