【摘要】：GPS欺騙式干擾具有發(fā)射功率小,抗干擾難度大的特點,分為轉(zhuǎn)發(fā)式干擾與產(chǎn)生式干擾。利用衛(wèi)星信號模擬器產(chǎn)生包含錯誤導航信息的GPS民用C/A碼欺騙信號,通過直接侵入和壓制式干擾輔助兩種方式進入接收機的捕獲跟蹤環(huán)路,對已定位的某款GPS接收機實施欺騙干擾。試驗結(jié)果表明,直接侵入方式下,通過合理控制欺騙信號功率,接收機定位被擾亂,但定位結(jié)果并未被成功欺騙至預設位置;壓制式干擾輔助方式下,接收機成功誤定位于預設位置,驗證了對GPS接收機進行欺騙式干擾的可行性。
[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.
