Abstract In work characteristics of the reception parametrical aerial working in a swirl are submitted. It is shown that occurrence cavitation leads to occurrence in the environment of a considerable dispersion of phase speed of distribution of waves. It is shown, in the liquid environment with vials except nonlinearity of hydrodynamic character there are the effects caused by nonlinear fluctuations of a vial. The received equations are applied to research of distribution of a wave of a rating in the reception parametrical aerial. Dependences of phase speed of a sound in sea water from frequency and concentration of air vials are resulted. Changes of the characteristic of an orientation in such environment for the parametrical reception aerial are shown.
