Abstract: The traditional adaptive nulling antenna array anti-interference algorithm can cause phase distortion, make the antenna phase unstable, and produce positioning error. Based on the analysis of the adaptive nulling antenna array anti-jamming algorithm, this article deduces the calculation method of its phase centre and the stage of real-time change, determines the phase centre error, and calculates the compensation value which can be used for the repositioning after correction. Simulation and experimental results verify the rationality and effectiveness of the algorithm, which can be used to improve the positioning accuracy of anti-jamming array antenna GNSS receiver.

Keywords: array antenna; phase centre error; anti-jamming; high precision; power inversion; GNSS; anti-interference; adaptive nulling antenna.
