摘要: 为了有效地实现振源方位估计,设计了由三个加速度传感器组成的三角形阵列时延系统;分别推导了基于单三角形阵列的定向算法及基于双三角形阵列的定距算法,并且分析了单三角形阵列时延系统的定向精度,从而探讨了单三角形阵列的定向精度与双三角形阵列的定距精度之间的关系;最后通过实验,验证了单三角形阵列对振源方位估计及双三角形阵列对振源距离估计的有效性。

关键词: 三角形阵列, 时延系统, 方位估计, 定向精度

Abstract: In order to effectively achieve vibration source bearing estimation, a triangle array time delay system composed by three acceleration sensors was designed. Localization algorithm and distance determination algorithm were derived for single triangle array and double triangles array respectively, and then the localization accuracy of single triangle array time delay system was also analyzed, so the relationship between localization accuracy and distance determination accuracy was investigated. The experimental results show that both vibration source position estimation by single triangle array and vibration source distance estimation by double triangles array are effective.

Key words: triangle array, time delay system, bearing estimation, localization accuracy
