| 摘 要： | 采用特征矢量（ＥＶ）法、ＭＵＳＩＣ法和ＥＳＰＲＩＴ等子空间方法，对拖线阵海试数据进行了处理研究，并和常规波束形成方法（Ｂａｒｔｌｅｔｔ法）、最大似然（ＭＬ）法进行了比较．通过拖线阵海试数据的处理，对应用子空间方法进行方位估计时所遇到的一些问题进行了研究．结果表明：子空间方法在水声中是一种具有应用前景的方法，尤其在短基阵就更具有优越性．

| Abstract: | This paper deals with tow array experimental data using subspace methods, e.g, cigenvector (EV) method, MUSIC method, ESPRIT method, etc, which are compared with Conventional Beam forming method (Bartlett), Maximus-likelihood (ML). Through processing of actual data, some problems applying subspace for bearing estimation are studied. The results show that the subspace methods will have prospective application, in the undeerwater accoustics, especially in the short array, as they have more advantages. |
