Multi-sources Distinguishing by Exploring Line Spectra with Single Acoustic Vector Sensor

摘要

摘要: 该文提出了一种通过单个矢量水听器低频线谱检测来分辨多目标的新方法，得出了矢量水听器线谱多目标分辨能力仅与线谱信噪比有关的结论。利用矢量水听器的低频测向能力，通过方位邻近准则实现了多线谱与多目标之间的关联，并采用滤波实现了多目标的分辨与航迹自动跟踪。实测舰船数据的仿真结果表明，该方法采用单个矢量水听器可以分辨互相间隔10的3个目标。方法简单有效，具有工程应用前景。

Abstract: A novel method of multi-sources distinguishing is proposed single acoustic vector sensor by detecting the line spectra. The distinguishing capability is found to be only relative to the output SNR of the line spectra. with the direction finding ability of acoustic vector sensor with in low frequency band, the association between the line spectra and the corresponding sources is established by using direction vicinity principle, the multi-sources distinguishing and auto-tracking is then realized with filtering. Simulations with sea trial data show that adjacent 3 sources with in 10 can be distinguished with single acoustic vector sensor. This method is simple and effective, thus has the prospect of engineering applications.
