Methods and system for determining viewing angles between two devices

摘要

The method involves determining virtual phase difference between receiving aerials (R1, R2) by linear combination of determined phase difference measurements for each wavelength. An integer value of ambiguity of the virtual phase difference is determined. The estimation of the path-length difference of radioelectric signals between the receiving aerials is determined, where the estimation is equal to specific equation comprising parameters such as integer value, virtual phase difference and virtual wavelength. Independent claims are also included for the following: (1) a method for determining essential characteristics of a system for determining a viewing angle between receiver and transmitter devices (2) a receiver device for determining a viewing angle (3) a system for determining a viewing angle.
