Aiming at the complicated and subjective issues of target ship traffic organization in the navigation simulator training scenario, the intelligent target ship system of the navigation simulator was designed. Firstly, the feature trajectories were obtained from the automatic identification system data, and the ship trajectories were clustered based on the DBSCAN algorithm, and the similarity was measured by normalized combination distance to construct the target ship planned route database.Secondly, the model database and index table of the target ship were constructed, and the optimization algorithm of the target ship was designed to match the optimal target ship for the planned route. Finally, the intelligent control algorithm of target ship was designed to realize the function of target ship route tracking and intelligent collision avoidance. The training results of the experimental scene show that the system can restore the actual traffic flow simulation scene and the independent collision avoidance between ships, reduce the workload of training scene compilation, and improve the training effect of navigation simulator.
