摘要
主要分析了声学多普勒计程仪测速误差的主要来源,并针对载体的姿态误差提出有效的补偿方法,对多普勒计程仪的安装偏差、波束方向误差和电路设计误差等固定误差,通过标定试验给出多普勒计程仪的补偿系数,并验证其有效性。
The main sources of error for the acoustic Doppler Velocity Log(DVL) were analyzed.The effective compensation method was proposed to solve the attitude error of vector.The DVL misalignment,beam direction error and circuit design error etc.were compensated through the calibration tests,which verified the effectiveness.
