阵列天线抑制欺骗式导航干扰信号方法研究
Research on Spoofing Suppressing Method Using Antenna Array for Navigation Signal
摘要
Abstract
In order to solve the problem of positioning errors caused by spoofing to the satellite navigation signals,a spoofing detection and elimination method based on antenna array is proposed.The carrier phase double difference measure-ment value of the receiving antenna array is used as the basis for interference detection.The direction vector of the spoofing is obtained by the single difference measurement value of the carrier phase.A method for improving the precision of the spoofing's direction is proposed too.The orthogonal vector is used to form a nulling in the direction of spoofing.By adjus-ting the beam direction,the array gain is formed in the direction of the signal to be measured,so as to achieve the purpose of resisting interference and enhancing the navigation signal at the same time.Using this method can effectively identify and e-liminate the spoofing in the navigation signal,which is suitable for aircraft navigation in complex environment.关键词
