Sea Test of a Parametric Acoustic Receiving Array at Stage I.
Abstract
The parametric acoustic receiving array (PARRAY) is a method of achieving highly directional reception of a low frequency acoustic wave in water using only two relatively small, high frequency transducers and some associated electronics. The PARRAY exploits the inherent nonlinearity of acoustic propagation through water to synthesize a continuous end-fire array directional characteristic without the need for a large number of hydrophones and a large quantity of beamforming circuitry. A sea test was conducted of the experimental PARRAY at the Stage I offshore facility of Naval Coastal Systems Center (NCSC), Panama City, Florida, during April and May 1979. This report summarizes objectives of that sea test, the experiments performed, and analysis of the data obtained during those tests. (Author)
