摘要提出了一种基于单个矢量水听器的二维波达方向估计方法，该矢量水听器由三个空间轴向垂直的振速水听器和一个声压水听器构成。 - 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
与传统的声压水听器相比，矢量水听器既能获得声场中的声压这一标量信息，又能获得声场中质点振速这一矢量信息，这为其信号处理带来更大的空间，因此矢量水听器及其相应的联合信息处理技术日益成为国内外科技工作者们研究的热点。 - 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
结合实际的应用情况，对矢量水听器构成的阵列进行了初步的探讨，利用本文前面部分所分析的基于单矢量水听器的方法，实现了阵元间距突破半波长上限的局限，并解决了角度估计的循环模糊问题，以较小的硬件代价和运算代价实现阵列孔径的扩展，提高估计精度。 - 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
