The Acoustic Doppler Current Profiler measures the water velocity using the physical Doppler shift principle. The transducer generates a pulse of sound at a known frequency that travels through the water and is reflected in all directions by particulate matter (e.g., sediment, biological matter, bubbles). Some portion of the reflected energy travels back at the transducer where the processing electronics measure the change in frequency. The Doppler shift measured by the transducer reflects the velocity of the water along the axis of the acoustic beam. The ADCP operates using three transducers generating beams with different orientations relative to the water flow then the measured velocity by each ADCP transducer is the projection of the 3D velocity onto the axis of its acoustic beam.

声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP）基于物理多普勒频移原理测量水流流速。该设备的换能器会发射已知频率的声脉冲，声脉冲在水体中传播，并被水中的颗粒物（如沉积物、生物颗粒物、气泡）向各个方向反射。部分反射能量会返回至换能器，此时处理电子设备可测量其频率变化量。换能器测得的多普勒频移，反映了沿声束轴线方向的水流速度。ADCP配备三个换能器，可生成与水流朝向各异的声束；每个换能器测得的速度，为三维水流速度在其对应声束轴线上的投影。
