Focused audile beamforming for high judgment and signal-to-noise percentage in the space rule is relevant for position applications. Analysis of the acoustic field founded by an emitter of complex geometry is a troublesome diffraction task. Rayleigh's complete provides a fundamental event to calculate the potential of the emitter field at each point precede. The purpose of the work search out create a numerical apparatus for manipulative the focused audile field of matrix emitters. A numerical approach to resolving the Rayleigh integral is used to the emitter, which is an array of beginnings with a short intuitiveness. The radiation pressure in the pertaining to a focus region is supposed as the sum of the offerings of individual discrete beginnings taking into account their focusing. The main and radial classification of pressure in the focal domain for disc and square emitters was resolved. The dependence of the time and width of the pertaining to a focus region on the capacity of the aperture of the disc emitter was obtained.
