欺骗式干扰将导致GPS接收机产生错误的定位信息。近些年来,对GPS欺骗式干扰信号抑制方法的研究取得了一些进展,但大部分研究都集中在发现欺骗式干扰信号上。提出了基于多天线的GPS抗欺骗式干扰信号方法,该方法不仅能发现欺骗式干扰信号,而且能对它进行抑制,同时增强真实信号功率。
欺騙式榦擾將導緻GPS接收機產生錯誤的定位信息。近些年來,對GPS欺騙式榦擾信號抑製方法的研究取得瞭一些進展,但大部分研究都集中在髮現欺騙式榦擾信號上。提齣瞭基于多天線的GPS抗欺騙式榦擾信號方法,該方法不僅能髮現欺騙式榦擾信號,而且能對它進行抑製,同時增彊真實信號功率。

GPS receiver will produce inaccurate position information when spoofing interference attacks GPS receiver. Nowa-days,The research on suppression method against GPS anti-spoofing interference signal has made some progress. However,a majority of techniques focus on finding the spoofing interference signals. A GPS anti-spoofing approach based on multi-antenna is proposed in this paper. This approach can not only find the spoofing signals,but also restrain them and enhance the power of each authentic signal.
