提出了基于声矢量传感器的分布式浮标网络定位系统,研究了不同应用背景下单个声矢量传感器的测向算法,推导了目标DOA估计的Cramer-Rao界,给出了分层海水介质中多个声矢量传感器的几何定位算法。数值仿真结果表明:(1)系统的定位性能强烈依赖于接收信噪比;(2)该系统适用于单一强声源的定位。
A distributed buoy network localization system based on acoustic vector sensor is proposed. The direction finding algorithm of single acoustic vector sensor under different application background is studied. The Cramer-Rao bound of target DOA estimation is deduced. Geometric Algorithm of Acoustic Vector Sensor. Numerical simulation results show that: (1) the positioning performance of the system strongly depends on the received signal-to-noise ratio; (2) the system is suitable for the localization of a single strong sound source.
