The invention provides a ship abnormal behavior recognition method based on navigation trajectory features. The method comprises the steps of motion feature rough judgment, channel conformity analysis, abnormal behavior detection and target alarm judgment. Through extraction, clustering, modeling and anomaly detection of ship navigation tracks, description and analysis of ship behaviors and real-time anomaly detection are realized, an alarm can be given at the initial stage of occurrence of ship abnormal behaviors, potential safety hazards can be found in time, and safe navigation of ships is ensured. Especially in navy military defense and electronic countermeasure, abnormal behaviors and abnormal targets of the ship can be effectively identified by detecting the navigation trajectory.

    本发明提出一种基于航行轨迹特征的船舶异常行为识别方法,包括运动特征粗判、航道符合性分析、异常行为检测、目标告警判断。通过对船舶航行轨迹的提取、聚类、建模和异常检测,来实现对船舶行为的描述和分析并实现实时异常检测,可以在船舶异常行为发生的初期做出警示,及时发现安全隐患,确保船舶安全航行。尤其是在海军军事防御与电子对抗中,通过对航行轨迹的检测,可以有效的识别船舶的异常行为和异常目标。
