摘要:

全球卫星导航系统（global navigation satellite system, GNSS）欺骗式干扰因其会导致GNSS输出错误信息以及隐蔽性强的特点，对舰艇编队航行安全构成重大威胁。传统的欺骗检测方法聚焦于单平台的信号特征分析及多传感器组合导航技术，并未考虑到编队内部多个平台信息的相互利用。为了有效利用编队内部多平台的相对测距信息，本文提出舰艇编队测距一致性欺骗干扰检测算法，通过对数据链通信测距设备与GNSS的间接测距信息差异进行分析，并构建形成检验统计量，结合观测数据实时监测异常，可有效检测变化非常缓慢的欺骗干扰；同时引入信任度评估机制对检测结果进行二次验证，有效降低误检概率。该方法有效利用了多个平台间的测距信息，为舰艇编队导航安全提供新思路。

Abstract:

Deceptive jamming of the Global Navigation Satellite System (GNSS) poses a significant threat to the navigation safety of naval formations due to its characteristics of causing incorrect information output by GNSS and strong concealment. Traditional spoofing detection methods focus on the analysis of signal characteristics of a single platform and multi-sensor integrated navigation technology, without considering the mutual utilization of information from multiple platforms within the fleet. To effectively utilize the relative ranging information among multiple platforms within the fleet, this paper proposes a ranging consistency spoofing interference detection algorithm for formation of ships. By analyzing the differences in indirect ranging information from data link communication ranging equipment and GNSS, and constructing a test statistic, combined with real-time monitoring of abnormal observations, it can effectively detect very slow-changing spoofing interference. At the same time, a trustworthiness evaluation mechanism is introduced to revalidate the detection results, effectively reducing the false alarm probability. This method effectively utilizes the ranging information among multiple platforms, providing a new approach for the safety of formation of ships.
