超声波定位系统是提供细粒度室内定位数据的流行解决方案。应用包括无线网络的增强路由、计算机辅助导航和位置敏感设备行为。然而，当前的超声波定位系统由于使用窄带换能器而受到限制。本文研究了宽带超声波在室内定位系统中的应用。宽带超声波发射器和接收器单元已经开发出来并进行了表征。利用这些单元构建两个具有不同架构的定位系统，可以突出并肯定宽带超声波在室内定位人员和设备方面的具体、实际优势。
Ultrasonic location systems are a popular solution for the provision of fine-grained indoor positioning data. Applications include enhanced routing for wireless networks, computer-aided navigation, and location-sensitive device behavior. However, current ultrasonic location systems suffer from limitations due to their use of narrowband transducers. This paper investigates the use of broadband ultrasound for indoor positioning systems. Broadband ultrasonic transmitter and receiver units have been developed and characterized. The utilization of these units to construct two positioning systems with different architectures serves to highlight and affirm the concrete, practical benefits of broadband ultrasound for locating people and devices indoors.
