| 摘 要： | 欺骗式干扰由于实现成本低、干扰能力强，成为GNSS中主流干扰来源，但现有GNSS抗干扰天线仅仅针对压制式干扰.根据欺骗式干扰检测获得的干扰到达方向信息，采用人为在该角度增加压制式干扰的方法，现有GNSS调零天线就可以在欺骗干扰角度形成方向图零陷，实现欺骗干扰抑制.通过对天线方向图和接收机扩频码同步仿真，验证了新方法的有效性.

| Abstract: | Nowadays spoofing is the dominant threats for GNSS receiver due to its low cost and high efficiency.However,the nulling antenna,which is widely used in GNSS receiver,can only mitigate the interference via high power.According to the DOA information of spoofing,some pseudo interferences are added to the received signal and imping on the antenna array from the same DOAs as the spoofing.Then the following traditional nulling antenna can suppress the spoofing since the beam pattern generate nulls at the DOAs of spoofing.Finally,the simulations of beam pattern and PN code synchronization illustrate the performance of the proposed method. |
