摘要
声学多普勒海流剖面仪(ADCP)是一种能测量三维垂直剖面流的高效仪器。当它固定在调查船上时,得到的海流数据要受到表面波动、螺旋桨的噪音和船壳汲入的漩涡的影响.为此,日本科技人员设计了一种用拖曳式运载体承载ADCP的新系统来测流,以消除上述干扰.这种拖曳式运载体深度和转动可控,拖曳电缆长800m,运载体的长、宽、高分别为2、2、1.5m,重360kg,最大速度为12kn.现场试验表明;这一系统性能优良,测得的数据有良好的精确度。
Acoustic Doppler Current Profiler(ADCP)is a high efficient inst- rument which is capable of measuring 3D current profile .When ADCP is mounted on a ship, the measured current data will be effected by surface wave, propeller noise and eddy induced by shiphull movement. For eliminating the above mentioned influences japanese engineers have designed a new ADCP system mounted on a towing vehicle for current measurement.The depth and rotation of the vehicle are controllable.The length of the towing cable is 800m The length, width and height of the vehicle are 2×2×1. 5m respectively. It is of 360kg in weight. The max towing speed is 12 knots. The in-situ experiment showed that the perfo- rmance and the measurement accuracy of this system are good
