摘　　要：该文提出了一种利用TCM2电子罗盘获取晃动平台的三态角:俯仰角、偏航角、翻滚角和3轴磁强度,温度等数据信息的方法,并对理想状态晃动轨迹进行分析,提出利用三态角信息描述平台轨迹的理论公式,符合电子罗盘对平台信息的描述,可以充分利用电子罗盘获取的信息研究分析平台晃动。最后利用自适应LMS算法跟踪平台的晃动情况,将平台实际轨迹和理想轨迹之间的误差补偿为零,即可以估计出晃动平台在任意时刻的姿态参数,在软件上实现晃动姿态的跟踪和补偿,这为平台准确定位目标提供了保障。A valid way for measuring the stance of the swaying platform is analyzed in this paper , which uses electronic compass（TCM2） to obtain the position of the swaying platform in the form of compass, pitch and roll and the information of magnetism and tempetature. An ideal swaying track is analyzed and a novel method for describing the platform using the three part of the angle stance is introduced. And the paper is based on the LMS algorithm of adaptive signal processing, used to track and compensate the swaying platform underwater. The simulation results obtained have proved the effectiveness of this method.
