THE FORMULAS OF AN ACOUSTIC CHANNEL OF AN ANGLE DUAL PROBES OF LONGITUDINAL WAVES FOR VARIOUS MODELS OF REFLECTORS IN A FAR FIELD
(pp. 4-13)

Abstract. Formulas of acoustic channels of an angle dual probes of longitudinal waves for several models of reflectors – a spherical hole, a notch, an infinite strip, a round flat bottom hole etc. in a far field are given, allowing to carry out calculations of signals at change of position of probes on a surface of the control concerning reflectors. For reflectors as lateral side drilled hole and spherical hole definition of an angle of probe and an angle of a direction on a point of reflection in a plane of the control is carried out by the decision of system from two transcendental equations. In formulas of acoustic channels for angle reflectors at the account of easing of longitudinal waves at their reflection from flat surfaces method of prof. I. N. Ermolov is used.

Keywords: angle dual probe, longitudinal wave, piezoplate, angle of probe, angle of a turn, directivity characteristic, probe axis, cylindrical reflector, angle reflector, flat bottom hole.
