摘要：
双向超宽带（UWB）定位方案是基于时间的UWB定位系统中广泛采用的三种设计集成过程之一。双向UWB定位的关键特性在于其能够在单一定位方案中按需同时服务于导航和跟踪任务。传统上，在无线定位系统中，由于各自实现过程中不同的应用场景和方法需求，导航和跟踪被视为独立的实体。因此，在单一方案中灵活或弹性地结合两种独特的定位视角（导航和跟踪）的能力，可被视为对传统基于位置服务观察方式的一种范式转变。本文从灵活且多功能的定位拓扑角度综述了上述双向UWB定位，并强调了其在该领域的潜力。为此，本文采用模块化过程全面描述了双向UWB定位方案的完整系统模型。文章还讨论了两个系统集成过程的演示性评估，并对该方案进行了SWOT（优势、劣势、机会和威胁）分析。此外，简要讨论了所提出的双向定位方案在5G/6G无线移动网络以及基于Wi-Fi精细时间测量的定位系统中实现精确位置估计的前景。
英文摘要：
A bidirectional Ultra-Wideband (UWB) localization scheme is one of the three widely adopted design integration processes commonly used in time-based UWB positioning systems. The key property of bidirectional UWB localization is its ability to serve both navigation and tracking tasks within a single localization scheme on demand. Traditionally, navigation and tracking in wireless localization systems were treated as separate entities due to distinct applicable use-cases and methodological needs in each implementation process. Therefore, the ability to flexibly or elastically combine two unique positioning perspectives (navigation and tracking) within a single scheme can be regarded as a paradigm shift in the way location-based services are conventionally observed. This article reviews the mentioned bidirectional UWB localization from the perspective of a flexible and versatile positioning topology and highlights its potential in the field. In this regard, the article comprehensively describes the complete system model of the bidirectional UWB localization scheme using modular processes. It also discusses the demonstrative evaluation of two system integration processes and conducts a SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis of the scheme. Furthermore, the prospect of the presented bidirectional localization scheme for achieving precise location estimation in 5G/6G wireless mobile networks, as well as in Wi-Fi fine-time measurement-based positioning systems was briefly discussed.
