The acoustic field generated by a pulsating source moving in the atmosphere along and perpendicular to the water-atmosphere interface at a subsonic speed is investigated. Calculated relationships are derived for the amplitude, frequency, and duration of a sound pulse recorded in both media in the vicinity of the interface. The spatial distribution of the amplitude of the acoustic field in the atmosphere and in the liquid is presented in the form of a two-dimensional relief to demonstrate its features and dependence on the speed and direction of motion of the sound source. The relationship between the characteristics of acoustic radiation and the average depth in the water area is analyzed.
