摘　　要：海洋内波与声场的相互关系是一个十分重要的研究课题。内波是影响声信道特征的重要因素;反之,受内波影响的声场也包含着海洋内波动力过程的信息。针对二者之间的关系,从工程的角度上介绍了利用声学多普勒海流剖面仪(ADCP)对海洋内波进行监测的原理和方法,并结合实际的海试情况给出声学多普勒海流剖面仪对海洋内波的监测结果,验证了方法的有效性。The relationship between ocean internal wave and acoustic field is a very important topic.Internal waves are an important factor that affects acoustic channel,whereas acoustic channel affected by internal waves also includes the information of dynamic processes of internal waves.According to this relationship,a detecting principle and method of ocean internal wave based on Acoustic Doppler Current Profile（ADCP） is introduced in this article.The effectiveness of this method is verified via the detecting result of ocean internal wave by ADCP in the sea trial.
