【摘要】：GPS欺骗式干扰具有发射功率小,抗干扰难度大的特点,分为转发式干扰与产生式干扰。利用卫星信号模拟器产生包含错误导航信息的GPS民用C/A码欺骗信号,通过直接侵入和压制式干扰辅助两种方式进入接收机的捕获跟踪环路,对已定位的某款GPS接收机实施欺骗干扰。试验结果表明,直接侵入方式下,通过合理控制欺骗信号功率,接收机定位被扰乱,但定位结果并未被成功欺骗至预设位置;压制式干扰辅助方式下,接收机成功误定位于预设位置,验证了对GPS接收机进行欺骗式干扰的可行性。
[Abstract]:GPS spoofing jamming has the characteristics of low transmitting power and great difficulty in anti-jamming. It can be divided into two types: forward jamming and production jamming. The satellite signal simulator is used to generate the GPS civil C / A code spoofing signal containing the wrong navigation information and to enter the acquisition and tracking loop of the receiver by direct intrusion and suppression interference. Spoofing interference on a GPS receiver that has been located. The experimental results show that the receiver location is disturbed by controlling the power of deceptive signal reasonably, but the location result is not successfully deceived to the preset position. The receiver was successfully mislocated in the preset position, which verified the feasibility of spoofing interference to the GPS receiver.
