摘　　要：根据本船的运动参数及连续两次观测所得到的目标船的相对方位和距离,运用避碰几何原理,在Matlab平台下建立了船舶避碰真运动模型,可以得到目标船运动参数及本船的避让措施和恢复航向的时机,并给出真运动轨迹图。文中还选择船舶会遇的典型实例对本模型进行了验证,结果表明,模型模拟的结果正确,对实际避碰行动有参考价值。In this paper, according to own ship＇s motion parameters and the target ship＇s relative bearing and distance that obtained from two times continuous observation, utilizing the geometrical principle of collision avoidance, on the platform of Matlab, the true motion model of the ship collision avoidance is established, which can be used to obtain the target ship＇s motion parameters, anti-collision measures through course alteration and the course safe-resuming time of own ship, meanwhile output the true motion trace graph. Finally, this model is verified through selecting four typical practical examples which ship will encounter. The results show that the model simulation conclusion is correct and comparing to the radar plotting, it is more accurate, time- saving and effort-saving, and can be also a great reference to guide the actual collision avoidance action.
