Marine target behavior analysis method and device and computer equipment

The invention provides a marine target behavior analysis method and device and computer equipment, and the method comprises the steps: carrying out the multi-space fusion of multi-source detection data, and obtaining a marine target, the multi-source detection data comprises the marine detection data obtained by at least two collection equipment, the marine target is used for describing navigation equipment with an abnormal equipment type or navigation equipment with an unknown equipment type; performing tracking processing on the marine target to obtain a navigation track of the marine target; on the basis of the navigation trajectory of the marine target, behavior analysis is performed on the marine target, and the behavior analysis is abnormal analysis of future behaviors/historical behaviors of the marine target, so that detection errors generated by single detection are reduced through spatial fusion of multi-source detection data, and the accuracy of behavior analysis of the marine target is effectively
