Abstract：In high dynamic environment, the conventional interference suppression algorithms based on covariance matrix are ineffective because of the dramatic change of interference Direction Of Arrival (DOA) in consecutive snapshots. In this paper, a high dynamic interference suppression algorithm with few snapshots for satellite navigation system is proposed to solve the problem of snapshot deficiency. By utilizing the sparse property of spatial spectrum, the DOAs of interferences are estimated by using few snapshots, even only one snapshot. Then the interference subspace is formed based on the estimated DOAs, and orthogonal subspace projection algorithm is used to suppress interference. Simulations demonstrate the effectiveness of the proposed algorithm.
