摘　　要：针对多波束测量中存在的声速误差问题,探讨了声速误差对多波束测量的影响以及影响表层声速和换能器动态吃水深度变化的主要因素,提出了一种旨在提高多波束测量精度的有效手段——温、盐、深探头的综合运用,以便实时测定表层海水的声速和换能器的动态深度吃水改正。The error of the sound velocity measured in water column is one of the most important factors influencing the accurate of bathymetry in the multi-beam echo sounder survey.The main influences on the sound velocity in the upper water column were researched.The dynamic draught of the transducer is also discussed.A synthesis application of temperature/salty/depth profilers which can measure the speed velocity and correct the draught in real time is proposed in order to improve the accurate of multi-beam echo sounder survey.
