The method for classifying and identifying the danger degree of the ship according to the target is reasonable in design, the problems of target loss and excessive danger judgment are solved by adopting a multi-data source mode, and the accuracy and objectivity of danger identification are improved. The method comprises the following steps: S1, performing large-range search by a radar when a ship sails, and collecting target motion state information; s2, setting a safe distance according to the navigational speed and the size of the ship, and verifying a target position obtained by processing a trace point of a reconnaissance radar and a radar image; s3, determining the danger degree of the screened targets which may need to be processed within the theoretical safety distance; and S4, tracking the target with the final danger degree from large to small. 本发明提供一种设计合理的根据目标对船舶的危险程度进行分类和识别的方法，在于采用多数据来源的方式，解决目标丢失和危险过度判断的问题，提高了危险识别的准确性和客观性。本发明包括如下步骤：S1：船舶在航行时由雷达进行大范围搜索，采集目标运动状态信息；S2：根据航速及船自身尺寸设置安全距离，对利用侦查雷达的点迹以及雷达图像
