With the continuous development of ship information technology, automatic identification system (AIS) plays an increasingly important role in marine traffic management and ship navigation safety. In this paper, a ship identification method based on AIS data is proposed to solve the problem of military-civilian type identification of ships. The method establishes a sensitive sea area model for the distribution of key points of ship trajectories, calculates the probability of military-civilian attributes of ships, and constructs a category classifier to judge the military-civilian attributes of ships. The proposed method uses cheap, all-domain coverage and high frequency AIS information to identify the military and civilian types of ships, which can detect and warn the threatening behaviors existing in the sea area in advance, provide support and auxiliary decision-making for subsequent response and disposal.
