热液冷泉区ADCP数据集

ADCP测量初步分析:声学多普勒海流剖面仪采用OS-38进行海流速度和方向的探测，它是通过发射声脉冲碰到水体里的悬浮体后产生后向散射信号，根据相控阵和宽带技术，获得后向散射信号中多普勒频移的大小和方向，通过相应计算获得流速信息。

Preliminary Analysis of ADCP Measurements: The Acoustic Doppler Current Profiler (ADCP) adopts the OS-38 system to detect ocean current velocity and direction. It operates by transmitting acoustic pulses, which generate backscattering signals after interacting with suspended matter in the water column. Leveraging phased array and broadband technologies, the magnitude and direction of the Doppler frequency shift in the backscattering signals are acquired, and current velocity information is obtained through corresponding computational procedures.
