声学多普勒流剖面仪(ADCP)是测量水柱内流场的有效工具。它还可以用来测量每一测量层的回声强度，然后将结果与悬浮物的形状和浓度相关联。本文提出了一种利用ADCP测量水下悬浮物浓度的方法。为了确定浓度和回声强度之间的关系，在水箱中使用ADCP和浊度传感器进行了实验室实验。然后在这方面构建了一个模型。然后用ADCP测量海底的回声强度，以验证水的浑浊度和荧光强度。最后对回声强度进行主成分分析(PCA)和主回归分析(PCR)。我们能够从ADCP的回声强度估计浊度和浮游生物的浓度。
The Acoustic Doppler Current Profiler (ADCP) is an effective tool for use in measuring the current field within the water column. It can also be used to measure the echo intensity in each measurement layer, and results can then be correlated with the configuration and concentration of suspended matter. This paper suggests a method for measuring the underwater concentration of suspended matter using the ADCP. To determine the relationship between concentration and echo intensity, laboratory experiments were conducted in water tanks using ADCP and turbidity sensors. A model was then constructed in this respect. The ADCP was then used to measure the echo intensity under the sea, to verify the turbidity and fluorescence strength of the water. Finally, principal component analysis (PCA) and principal regression analysis (PCR) were applied against the echo intensity. We were able to estimate concentration of turbidity and plankton from echo intensity of ADCP.
