| 摘要: |
| 为了降低天线阵接收机欺骗干扰检测方法的计算量，提出一种信号解扩前的欺骗干扰检测方法。该方法利用不同天线上信号和噪声相关性的差异，在信号解扩前估计其功率，从而进行欺骗干扰检测。仿真结果表明，该方法在降低运算量的同时，具有良好的检测性能。 |

| Abstract: |
| In order to decrease the computation complexity of the spoofing detection methods for antenna-array GNSS(global navigation satellite system) receivers, a spoofing detection method before signals despreading was proposed. The correlation difference of signal and noise on different antenna elements was used in signal power estimation. Then the spoofing was differentiated according to the estimated signal power. Simulation result indicates the effectiveness of the proposed method and the reduction of computation complexity. |
