Method and system for locating interferences affecting a satellite radio-navigation signal

摘要

The method involves determining an intercorrelation matrix of signals (201) received by elementary antennas of an array. A set of pointing vectors is determined (203) in pointing direction of each antenna, where components of pointing vectors are antenna gains. A power of the signal received in the direction is calculated (204) for spatial/spatio-frequency assumption. Searching for maxima among the calculated power and locating interfering sources is performed (205). Ambiguity resolution is performed (206) to eliminate the maxima relating to an ambiguity resulting from geometry of the array. An independent claim is also included for a satellite-based radio-navigation system.
