The paper presents an underwater source radiating biharmonic wave of finite amplitude. The source is designed as an array of many elements. Results of experimental investigations allow to assess the pressure field distribution of examining source. Special attention was paid to the observation of phenomena in the area of jorming nonlinear waves. Two transmitting arrays were used, both consisting of 16 circular transducers. The resonant jrequency of radiaiing elements equals to 600 kHz or 1.5 MHz, respectively. The jrequency range of the first of the sources is 540 kHz - 660 kHz; and of the second 1.2 MHz - 1.8 MHz. lnvestigation was carried outjor various pressure values at the radiating surface.
