摘要
自适应调零技术能有效提高卫星导航接收机抗干扰性能,具有重要的应用价值。介绍了基于空时联合处理的自适应调零算法,建立了七元圆阵仿真模型,进行了抗干扰算法仿真和零陷能力分析。仿真结果表明:空时联合自适应调零算法能抑制多个干扰信号,具有空时二维域上剔除干扰的能力,可以显著提升导航接收机的抗干扰性能。
The adaptive nulling technology can efficiently improve the anti-jamming performance of satellite navigation receivers,which has important application value.The adaptive nulling algorithm based on joint spacetime processing technology is introduced.Seven-element circular array simulation model is built.The anti-jamming algorithm is stimulated,and the nulling ability is analyzed.The simulation results show that several interferences can be restrained by space-time processing adaptive nulling algorithm,which can eliminate interference in space-time two-dimensional domain,and can remarkably improve the anti-jamming capability of navigation receivers.
