Research on the Impact of Array Anti-interference Antennas on RTK Positioning and Compensation Methods

This article explores the impact and compensation methods of RTK positioning from a physical perspective. Firstly, we need to consider the correction of amplitude and phase errors between array channels, which will be explained through actual testing; we need to further consider the inconsistency between RF channels, as the deviation caused by channel inconsistency needs to be balanced; After satisfying the consistency of channel amplitude and phase, it is finally considered that different directions of incident signals are accompanied by different antenna equivalent phase centers, and the offset correction of the antenna equivalent phase center needs to cover the entire direction of the incident signal.
