摘　　要：文章提出一种基于单孔径双极化天线的卫星导航信号抗干扰方法,推导了三维空间极化信号模型,并对算法的性能进行了详细的讨论。新方法仅占用单个天线位置,在不降低卫星信号质量的前提下,能有效抑制窄带或宽带干扰。为增强小型设备导航信号抗干扰能力提供了更为有效的解决方案。In this paper, polarize signal model in three-dimensional space is derived. An anti-jamming algorithm of satellite navi- gation signal based on single dual-polarized antenna is proposed, and the performance is discussed in details. Only occupying single an- tenna position, the new algorithm is able to cancel either narrow jamming or wide jamming while not damaging the navigation signal quality. It provides a more efficient solution for improving small volume equipment navigation signal anti-jamming ability.
