Abstract:
In this paper, Global Navigation Satellite System (GNSS) jamming nulling scheme using jamming-free subspaces is presented to overcome the jamming attack. It is based on the adaptive beamforming using array antennas. The eigenvalue decomposition (EVD) of the covariance matrix is used for separation between the jamming subspaces and the others. The proposed scheme determines the array weights by the jamming-free subspaces, which are composed of all subspaces except all jamming subspaces. The simulation results demonstrate that the proposed scheme nulls the jamming signal and receives all Global Position System (GPS) signal under the jamming environment
