基于软件的GNSS转发式欺骗系统的仿真实现

摘要

According to the basic theory about software receiver and retransmitted spoofing system,GNSS retransmit-ted spoofing system is designed based on software,a single channel of the real,spoofing and mixed signal,different jam-ming to signal ratio and delay distance is set and multi-channel signals are compounded.Through simulation,respectively in the acquisition,tracking and locating results periods,it verifies the correctness and reliability of GNSS retransmitted spoofing system based on software.%根据软件接收机与转发式欺骗系统的基本理论,基于软件设计了GNSS转发式欺骗系统,生成了单通道的真实、欺骗和混合信号,设置了不同的干信比和延时距离,并合成了多通道信号.通过仿真,分别在捕获阶段、跟踪阶段与定位结果阶段验证了该基于软件的GNSS转发式欺骗系统的正确性与可靠性.
