天线阵载波相位双差的欺骗干扰检测技术
Spoofing detection technique on antenna array carrier phase double difference
摘要
Abstract
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.关键词
