Abstract

Ultra wideband (UWB) positioning systems are increasingly used in indoor environments since commercial systems can provide 3-D accuracy of a few centimeters. Many applications exist in medicine for UWB positioning which includes tracking personnel, assets, and surgical navigation. We have designed a UWB positioning system with millimeter accuracy. Certain applications, including surgical navigation, have even more stringent accuracy requirements in the sub-millimeter range. Many challenges must be overcome to achieve sub-millimeter accuracy including indoor multipath interference, system clock jitter and drift, local oscillator phase noise, sampling-rate limitations, and phase center error. This paper discusses sub-millimeter accuracy in UWB positioning for medical applications and outlines key challenges faced in achieving it with our UWB positioning system. Solutions to these challenges are also outlined followed by a discussion of future work needed to integrate the entire system.

室内医疗环境超宽带定位实现亚毫米精度

超宽带(UWB)定位系统越来越多地用于室内环境，因为商业系统可以提供几厘米的三维精度。超宽带定位在医学上有许多应用，包括跟踪人员、资产和手术导航。我们设计了一个毫米精度的超宽带定位系统。某些应用，包括手术导航，在亚毫米范围内有更严格的精度要求。要实现亚毫米精度，必须克服许多挑战，包括室内多径干扰、系统时钟抖动和漂移、本振相位噪声、采样率限制和相位中心误差。本文讨论了医疗应用中超宽带定位的亚毫米精度，并概述了我们的超宽带定位系统实现亚毫米精度所面临的主要挑战。还概述了这些挑战的解决方案，然后讨论了整合整个系统所需的未来工作。
