摘要
声矢量传感器可以同时获取声波场的声压和振速信息。因振速是一个矢量,因而单个矢量传感器就能够提供声场的方位信息,为小尺度声传感器的设计提供了可能。论文首先对单矢量传感器目标定向的原理进行了研究,在单频信号处理的基础上扩展到实际中的宽带随机信号的处理,并进行了仿真分析研究。
The acoustic vector senso can provide the information of the acoustic pressure and acoustic particle velocity. Because acoustic particle velocity is a vector, the information of the direction can be obtained with the help of only one vector sensor. This makes it possible to design a smaller sensor. In this paper, the theory of object localization of single vector sen- sor is studied at first, and the single-frequency signal transaction is extended to wide-band signal transaction. The simulation analysis is conducted.
