Besides the size and shape of antenna arrays, the correlation between multipath components and a desired signal restricts the use of array processing techniques for Global Navigation Satellite System (GNSS) multipath mitigation. A new method, based on a moving antenna array, to synthesize a larger array and increase its degree of freedom is proposed. Furthermore, a spatial filter is applied to this synthesized array to prevent the signal cancellation phenomenon and mitigate the multipath components.
