METHOD OF MONITORING DIRECTIVITY OF PARAMETRIC RADIATION

摘要

FIELD: parametric sonic sources. SUBSTANCE: number of sonic-conducting electro-conducting plates-electrodes is introduced into area of interaction of pumping waves of parametric sonic source for routine monitoring of width and shape of directional patterns of parametric radiation. Plates-electrodes have different shapes and curvature of surfaces; there are different holes onto surfaces of plates. Row of preset shapes of directional patterns is provided as a result when parametric radiation is formed onto the layer of boundary bubbles, which bubbles are formed onto corresponding plate when applying pulse voltage to the plate with preset amplitude and relative pulse duration. EFFECT: improved efficiency of operation.
