摘　　要：针对动态环境下舰船瞬时运动信息对其自身操纵性的影响,提出一种舰船运动信息的即时测量方法。分析了航行状态下舰船运动情况,总结了测量瞬时运动的实施方案并给出运用于测量瞬时速度信息的数字高通滤波器具体参数,并利用计程仪辅助惯性导航系统实现对测量结果的进一步强化。结合舰船工作环境设计了转台试验,结果表明:提出的动态环境下舰船瞬时速度测量方法具有较高的工程实践意义。According to the maneuverability of ship impacted by the instantaneous line motion, a novel measurement technology about was proposed. The implement scheme of instantaneous line motion was summarized and the parameter of filter was calculated. In order to improve the measurement result, the doppler log and inertial navigation system were combinated. The multi-functional platform in the laboratory was designed to testify the method. And the experiment results show that, the ship＇s heave information can be measured accurately by the measurement technology about the heave, and the measurement method has the higher feasibility.
