GPS anti-jamming utilizing dual-polarized antenna

Abstract

In this paper, an anti-jamming algorithm based on single dual-polarized antenna is proposed. The three-dimensional space polarization model is derived. The performance of the proposed algorithm is discussed in details. In the condition of not reducing the satellite signal quality, the new algorithm can deal with both narrow and wide band jamming, while only occupying one antenna space, and it provides a new proposal to improve the anti-jamming ability of small navigation equipment.
