Application of Parametric Acoustic Receiving Array to Underwater Acoustic Measurement

Abstract

The Parametric Acoustic Receiving Array achieves the directional reception characteristics through an end-fire array of virtual sources by the use of only two transducers (pump and hydrophone). With a radial size much smaller than linear receiving array whose radial size is too wide to fit in laboratory measurement of low frequency transducers, and with the ability of totally suppressing the inversely traveling signals, parametric acoustic receiving array can be used to measure low frequency complex waveform signals with large pulse length and broad bandwidth in reverberant tank. This paper gives a detail analysis and setups for this application.
