Title:
CIRCULAR POLARIZED ANGLE OF ARRIVAL MEASUREMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/022340
Kind Code:
A1
Abstract:
Methods and systems are disclosed and include receiving, at a plurality of azimuth angles, a signal via a first communication channel and a second signal via a second communication channel. The method includes determining a plurality of first and second communication channel phase angle differences of the antenna system that each correspond to one of the plurality of azimuth angles. The method includes generating a first reference curve and a second reference curve based on the plurality of first and second communication channel phase angle differences, respectively. The method includes determining a first set and a second set of phase difference limits, and for each set, the method includes: identifying a minimum and maximum capping region; determining a minimum phase difference limit based on a central location of the minimum capping region; and determining a maximum phase difference limit based on a central location of the maximum capping region.
