Abstract

Methods for determining the angular orientation of objects using interferometric measurements of different-frequency signals reflected by corner reflectors of satellite systems are considered. Determining the angular orientation of objects is one of the most common ways to expand the functionality of the consumer equipment of satellite radio navigation systems. The proposed method provides the determination of the angular orientation of a distant object based on the results of the analysis of the frequency spectrum of the reflected signal. The method is implemented using corner reflectors consisting of mutually orthogonal plane-parallel plates of different optical thicknesses. Each face (plane-parallel plate) of the corner reflector forms a unique frequency spectrum of the reflected signal. The desired value of the angular orientation is determined based on the analysis of the frequency spectrum of the recorded reflected signal and the criterion of maximum similarity of the spectrum of a certain orientation of the corner reflector faces. With normal incidence of the probing beam on a plane-parallel plate of a corner reflector, only one frequency is present in the spectrum of the recorded signal. The appearance of only one frequency, determined by the optical thickness of the reflecting plate, serves as a criterion for the orthogonal orientation of the corner reflector and the distant object, respectively.
