随着卫星导航技术的飞速发展，卫星导航系统在各个领域的应用越来越广泛，然而这种星基无线电导航的方式易受干扰，因此研制具有高接收灵敏度并具有抗干扰性能的卫星导航接收机是当前阶段需要迫切解决的一个重要问题。从阵元形式选择及阵列拓扑结构、天线阵元互耦及通道失配影响角度进行了研究，并对抗干扰阵列接收机射频链路进行了详细设计，所述的7阵元抗干扰阵列接收机的设计方法和研究成果对于实用化的阵列抗干扰系统具有一定的借鉴意义。

Along with the rapid development of satellite navigation technology,military system is increasingly depended on satellite navigation system.But satellite signals are very easy to be jammed.Therefore,it is imminently needed to develop the satellite navigation receiver with high receiving sensitivity and anti?jamming capability.In this paper,the design of anti?jamming RF receiver with array antennas is studied from aspects of array element form selection,array topological structure,antenna array element cross coupling and channel mismatch effects,and its RF link is designed in detail.The design method and research result of the mentioned receiver with seven array antennas can be referenced in the practicability of anti?jamming system with array antennas.
