摘要
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。
According to the basic theory about software receiver and retransmitted spoofing system, GNSS retransmitted spoofing system is designed based on software,a single channel of the real, spoofing and mixed signal, different jamming 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.
