چکیده
The prediction of ship location has become an increasingly popular research hotspot in the field maritime transportation engineering, which benefits safety supervision and security. Existing methods based on motion characteristics have a large uncertainty cannot guarantee trajectory accuracy target ship. An improved method using k-nearest neighbor (KNN) is proposed this paper. expanded circle area latest point first generated to find reference points with similar movement constraints distance time intervals. Then, top neighbors are determined degree similarity. Relationships between each calculated. predicted can then be by weighted calculation locations all at their relationships Experiments 10 min, 20 30 min were conducted. correlation coefficient error for three experiments was 0.992, 0.99, 0.9875, respectively. results show that multiple nearest movements provide better accuracy.
