摘要
为了进一步加强北斗卫星定位系统的抗干扰应用,立足“导航战”理念,提出电磁干扰环境下北斗卫星定位抗干扰策略:在总结北斗卫星信号结构和特性的基础上,查找北斗接收机面临人为干扰的薄弱环节,并重点对压制式、欺骗式和组合式干扰的机理、特点等进行分析;结合“导航战”3种属性进行逆向思维,从可用信号增强、干扰信号抵消、其他定位辅助等3个角度设计抗干扰总体策略;最后针对接收机抗干扰,提出一种“圆形阵列天线/空时域滤波”的压制式干扰对抗策略,以及惯导辅助定位、基于宽窄巷组合的载波相位差分等2种欺骗式干扰对抗策略。研究结果可为“导航战”理念实战转化和接收机抗干扰相关研究提供参考。
In order to further inhance the anti-jamming application of BeiDou navigation satellite system(BDS),the paper proposed the anti-jamming strategy of BDS under electromagnetic interference environments based on the concept of navigation warfare:on the summarization of BDS signal structure and characteristics,the vulnerability of BDS receivers to man-made interference was found,and the mechanism and characteristics of clamped,spoofing and combined jamming were analyzed;then,with three attributes of navigation warfare for reverse thinking,the overall anti-jamming strategy was designed from three aspects of signal enhancement,signal cancellation and auxiliary positioning;finally,three strategies for receiver anti-jamming,including the suppressive jamming strategy based on circular array antenna and space-time filter,and the deceptive jamming strategies based on inertial navigation assisted localization and carrier phase difference of wide-narrow lane combination,were put forward.Results could provide a reference for the relate research of the practice transformation from concept of navigation warfare and anti-jamming of receivers.
