Within the framework of solving the problem of increasing the effectiveness of the directional properties of adaptive systems with parametric sonar emitting antenna in the results of generalization of theoretical and experimental studies of the effect of hydro-irregularities on the characteristic parameter of the antenna. A comparison of the results of calculations of the antenna directivity characteristic parameter derived from the model Khokhlova-Zabolotskaya-Kuznetsova, with the results of experimental measurements of the directional properties of the parametric array. We obtain the normalized dependence of the width of the parametric characteristics of the antenna by lowering the difference frequency from the center frequency of the pump waves of 5 to 16 times. The influence of changes in the speed of sound in the direction of the parametric array. We obtain the normalized dependence of the width of the antenna characteristics of the parametric values of the sound velocity at the surface of the pump transducer. It was found that the greatest impact on the characteristic parameter of the antenna has a change in the speed of sound to a distance equal to the lengths of 1-2 zone diffraction of the pump waves.
