Abstract :
Smart jammer is one of the most threat interferences for the GPS receiver, so a smart jammer suppression algorithm is proposed in this paper, which combines spatial amplitude and phase estimation(APES) method and high resolution coherent subspace estimation method. The new method can resolve the problem that spatial APES is unable to cancel multiple coherent interferences, and also provide the accurate GPS signal estimate. Simulation results show that the feasible of the proposed method.
