声学多普勒海流剖面仪(ADCP)的开发,以获取水流速度,以及深度依赖的回波强度。由于水下目标的后向散射强度可以从测量的回波强度估计,ADCP可以用来估计浮游生物的种群和分布。在这项研究中,在水箱中的气泡群的后向散射强度估计使用商业ADCP作为概念验证。具体而言,在后向散射强度和气泡存在的持续时间的时间变化进行了定量评估。此外,基于所获得的分布特性,使用PDPA(相位多普勒粒子分析仪)来表征人造气泡的PDSL(群体密度谱水平)和VF(空隙率)。
Acoustic Doppler current profilers (ADCPs) were developed to acquire water current velocities, as well as depth-dependent echo intensities. As the backscattering strength of an underwater object can be estimated from the measured echo intensity, the ADCP can be used to estimate plankton populations and distributions. In this study, the backscattering strength of bubble clusters in a water tank was estimated using the commercial ADCP as a proof-of-concept. Specifically, the temporal variations in the backscattering strength and the duration of bubble existence were quantitatively evaluated. Additionally, the PDSL (population density spectrum level) and VF (void fraction) of the artificial bubbles were characterized based on the obtained distribution characteristics using a PDPA (phase Doppler particle analyzer).
