惯导辅助的三元天线阵欺骗干扰检测算法
Detection of spoofing threats by inertial assisted three elements antenna
摘要
Abstract
DOA (direction-of-arrival) discrimination is one of the most effective spoofing detection methods.There are two forms of DOA, one is the carrier phase single difference and the other is the carrier phase double difference.However, the carrier phase single difference cannot be used in the motion vector, and the carrier phase double difference will be ineffective in detecting single spoofing signal or multi-elements spoofing transmitter.In order to solve this problem, a method based on the inertial assisted three elements antenna was introduced.This method was applied to motion vectors, the motion vectors using this method can detect the spoofing only by means of moving a distance during a certain time.This method not only can be effective for several spoofing signals from the same antenna, but also can detect single spoofing signal or multi-elements spoofing transmitter with strong ability.The proposed spoofing detection method was verified to be effective through theoretical analyses and simulation tests.The results indicate that the longer the displacement distance of the receiver antenna is, the better the spoofing detection performance of the proposed method is;the closer to spoofer from the receiver antenna is, the better the spoofing detection performance of the proposed method is;the more vertical between DOA and antenna displacement direction is, the better the spoofing detection performance of the proposed method is.关键词
