Multipath mitigation is still a critical problem that must be resolved, especially short delay multipath. Research on multipath mitigation is reported and a multipath limiting antenna array including the algorithm is discussed. The carrier phase data of the receiver are subjected to forward-backward spatial smoothing to decorrelate the signals. The multiple signal classification (MUSIC) algorithm estimates the direction of the satellite signal and the direction of the multipath. Based on the direction of arrival (DOA), the beamforming maximizes the gain in the satellite signal direction and places nulls in the multipath directions. Compared to other beamforming algorithms, the method presented places nulls in the multipath directions and obtains high gain in the satellite direction. At the same time, the phase is not changed during the vector weighting method. The multipath limiting antenna array discussed resolves the problem that the short delay multipath cannot be reduced in signal processing multipath mitigation technology and that in the process, the phase in the direction of the satellite signal is not changed. An extra carrier phase measurement error of the receiver is not introduced, and a phase correction after beamforming is not necessary. The multipath limiting antenna array and the algorithm can provide support for the high-performance satellite navigation system.
