A Two Stage GPS Anti-jamming processor for Interference Suppression and Multipath mitigation
Global Positioning System (GPS) has found wide application in many areas. However, due to the low power of the received signal, GPS is susceptible to a variety of interferences and multipath. In this paper, a two stage GPS anti-jamming processor based on adaptive arrays is proposed. Firstly, the array received signals are projected onto the orthogonal subspace corresponding to interference to suppress interferences. Then the interference free signals are further processed by a conventional data-independent beamforming to enhance the GPS direct-path signal and mitigate GPS multipath signals. Simulation results are provided to demonstrate the performance of the proposed algorithm.
