A new direction of arrival estimation method is proposed using a single vector hydrophone , which is composed of three spatially co - located but orthogonally oriented velocity hydrophone plus another co - located pressure hydrophone
Compared with the pressure hydrophone , vector transducer can provide both the information about pressure ( scalar quantity ) and particle velocity ( vector quantity ) of the sound field , which offers more possibilities for signal processing . so vector transducer and its signal processing have attracted the attention of researchers both native and foreign . in this thesis , a method of correlation equations for pressure gradient transducer is presented , and the estimation of multi - signal parameters with single vector transducer is given
And more aperture extension is achieved in this novel esprit - based two - dimensional angle estimatio n scheme using a uniform rectangular array of vector hydrophones spaced much farther apart than a half - wavelength . this proposed scheme and the attendant vector - hydrophone array outperform a uniform half - wavelength spaced pressure hydrophone array with the same aperture and slightly greater number of component hydrophones by an order of magnitude in estimation standard deviation
A vector hydrophone is composed of two or three spatially co - located but orthogonally oriented velocity hydrophones plus another optional co - located pressure hydrophone . this paper introduces an underwater acoustic eigenstructure esprit - based algorithm that yields closed - form direction - of - arrival ( doa ) estimates using a single vector hydrophone
