摘　　要：针对ADCP海上标校问题,深入分析多普勒流速测量原理,并结合工作实践介绍一种海上标校方法,方法首先利用20 n mile长测线计算安装偏角与振幅因子,然后利用“4”字线内符合试验与外符合试验验证校准数据的准确性。多次海上试验表明,该方法标校精度高、作业流程简单,具有较好的实用价值。在此基础上依托大量工作经验并结合理论分析,给出一种ADCP平均时间、盐度、声速的参数设置,并通过海上试验验证了任何深度的水平流速计算都只需要换能器处声速值的结论,为ADCP的实际使用提供有力参考。Focusing on the ADCP offshore calibration problem,the Doppler flow rate measurement principle is analyzed.Combined with the working practice,a sea marking method is introduced which uses 20 n mile long line to calculate the installation angle and amplitude factor.Based on work experience and theoretical analysis,a parameter setting method of ADCP average time,salinity and sound velocity is presented.The conclusion is drawn that the horizontal flow rate calculation at any depth only requires the sound velocity value at the transducer.The conclusion can be a strong reference for ADCP applications.
