Application of Sound Reflection for the Confirmation of the Possibility of Calibrating Vector Receivers in Undamped Tanks

Resumo

We study the causes complicating the application of the tone-burst method for the calibration of underwater vector sound receivers. We describe an experiment performed to confirm the correctness of the procedure of calibration of a vector receiver by the method of moving complex weighted averaging when the sensitivity measured in the reverberating sound field cannot be compared with the results of other independent methods. As a criterion, we use the correctness of measurements of the parameters of distortions introduced by the sound waves reflected from the water–air interface in the direct wave of the emitter. The proposed technique makes it possible to experimentally establish the possibility of selection of the vector quantity of the direct wave from the emitter in the reverberating sound field formed in the water tank within the frequency range overlapping the range of the tone-burst method and extended to the frequencies of the chamber of standing sound waves.
