摘要
介绍一种新的信号分析方法──“视在方位序列分析”方法。介绍了该方法的理论基础和基本思想，以及在水声信号处理领域的应用价值。提出了一种新型检测器──视在方位序列方差检测器（ＶＰＢＤ）。在混响背景条件下，该检测器具有比ＶＩＦＤ更优良的性能。通过计算机仿真研究和海试数据处理验证了其有效性。
A new signal analyzing method, named pseudo bearing sequence analysis, is proposed in this paper. Thetheoretical foundation and basic ideas of the method, as well as its practicable applications on the area of underwateracoustic signal processing, are introduced. A new type of signal detector named VPBD is presented, which is superiorto VIFD in the reverberation background. The validity of the proposed method has been confirmed by means of bothsimulations in computer and the practical processed trial data.
