Abstract
The possibility of using phase conjugation in ultrasonic tomography to reconstruct the distribution of liquid flow velocities is discussed. The results of experiments aimed at reconstructing the distribution of flow velocities in the vortex cross section by the back projection method are shown. A mathematical model of acoustic wave propagation in a medium with a stationary liquid flow and an algorithm for reconstructing the velocity distribution using a 64-element acoustic antenna have been developed. The results of numerical experiment are discussed.
