摘　　要：转发式欺骗干扰因其欺骗干扰功率低,隐蔽性强的特点已成为未来导航对抗战的一个新课题,但是其系统实现复杂,技术难度大。多通道卫星导航信号实时转发系统能够实现对多通道卫星导航信号的实时采集和可控延时转发,为转发式欺骗干扰相关技术问题的研究提供了基本的实验平台。分析了多通道卫星导航信号实时转发系统的基本原理,提出了多通道卫星导航信号实时转发系统的设计方案,并利用NI平台对设计方案进行了初步的验证,验证结果表明该方案具有可行性。Retransmitted jamming has become a new topic for future navigation countermeasure because of its low transmit power and strong concealment,but its system implementation is complex and some technical points are difficult. Multi-channel satellite navigation signal retransmitting system in real-time can achieve real time acquisition and retransmission in adjustable delay for multi-path satellite navigation signal,and provide basic experimental platform for other technique issues of retransmitted jamming. The basic principle of multi-channel satellite navigation signal retransmitting system in real-time is analyzed,and design scheme of multi-channel satellite retransmitting signal system in real-time is proposed. Design scheme is verified preliminarily with NI platform,and results of the confirmation indicate that the design scheme is feasible.
