【摘要】 本文给出了两种基于矢量传感器的被动定位方法。一般来说,对目标进行被动定位可以通过方位信息或时延信息来实现。单个矢量传感器就可以实现目标方位估计,而对多个矢量传感器接收的信号进行互相关运算即可得到目标对各矢量传感器的时延信息。本文先给出了利用方位信息进行被动定位的方法,然后给出了利用分布式矢量传感器进行方位-时延信息联合被动定位的新方法,并通过仿真分析对这两种方法的定位性能进行了比较。更多还原

【Abstract】 This paper provides two passive methods for source localization based on acoustic vector sensor. Generally, the localization of a target requires the estimation of direction of arrival (DOA) or the estimation of time difference of arrival (TDOA). The estimation of DOA can be realized by using an acoustic vector sensor, while the calculation of the cross-correlation function for several such sensors can give TDOA information. This paper at first introduces the method applying DOA information. Then it derives a novel method for source localization, which uses the combination of DOA and TDOA from distributed acoustic vector sensors. The simulation results of the performance of the two methods are presented.更多还原
