针对采用单一发射天线的导航信号欺骗干扰，研究了基于天线阵载波相位双差的欺骗干扰检测技术，采用代数方法证明了三元非线阵是进行导航信号到达角无模糊解算的最少阵元数和阵型要求，并以相应阵型为基础，提出了基于天线阵载波相位双差的欺骗干扰检测量构造方法，给出了检测性能的分析方法，定义了用于限制检测性能下降的最小检测门限。采用蒙特卡洛方法对所提检测方法的检测性能进行了仿真，结果验证了理论分析的正确性。

For the navigation signal spoofing signal transmitted with single antenna,a spoofing detection technology based on multi-antenna carrier phase double difference was stuied.Three-antenna array,in which not all antennas are placed in direct line,was proved to be the minimum antenna array which can solve the navigation signal arrival angle without ambiguity.Based on the corresponding antenna array,a method for constructing spoofing test statistic based on multi-antenna carrier phase double difference was proposed,and the detection performance analyzing method was presented.Then,the minimum detection threshold was defined for limiting the decrease of the detection performance.Finally, detection performance of the proposed detection method was simulated by Monte Carlo method,and the results validate the correctness of theory analysis.
