摘要: 为分析全球卫星导航系统(GNSS)中存在欺骗干扰的场景下调零抗干扰天线的反欺骗性能，推导出在快拍数有限的情况下，功率倒置(PI)算法利用调零天线处理后输出真实信号和欺骗信号功率的理论公式. 详细分析了欺骗信号到达天线阵口面的功率对真实信号和欺骗信号输出功率的影响，通过欺骗抑制比这一指标来衡量PI自适应调零天线的反欺骗性能. 分析得出：即使欺骗信号功率在噪声水平之下，使用PI算法的自适应调零抗干扰接收机依然能对欺骗干扰进行抑制，在欺骗信噪比高时，抑制效果更加明显. 最后通过仿真和硬件平台实测验证了结论的正确性.

Abstract: In order to analyze the anti-spoofing performance of the nulling anti-jamming antenna for Global Navigation Satellite Systems (GNSS) in the spoofing interference scenario, the theoretical formula for the power of authentic and spoofing signal is derived which are processed by the nulling antenna using power inversion algorithm with limited snapshots. The influence of the power of the spoofing signal arriving at the antenna array interface on the output power of the authentic and spoofing signal is analyzed in detail. And the spoofing suppression ratio is used to measure the anti-spoofing performance of the adaptive nulling antenna using power inversion algorithm. The analysis shows that even if the power of the spoofing signal is below the noise level, the adaptive nulling anti-jamming receiver using power inversion algorithm can still suppress the spoofing. And when the spoofing signal-to-noise ratio is high, the suppression effect is more obvious. Finally, the conclusion is verified by simulation and hardware platform test. -
