Novel UWB systems

超宽带（UWB）是一种新兴的近距离设备技术，在无线通信、雷达、定位和安全应用方面具有潜在的优势。超宽带通信设备可用于无线分布服务，如电话、电缆和计算机网络，遍及整个建筑物或家庭。基于其低成本和高速数据传输能力，超宽带在家庭和商业市场都有潜力，并且可以很好地适用于各种视频分发应用。超宽带雷达在医学成像雷达和穿壁探测雷达中有广泛的应用。除了这些应用之外，超宽带技术还将在各种监控应用中得到应用。本研究计划的主要目标是为无源超宽带元件（如天线、滤波器、混合耦合器等）开发新的设计指南。本研究也著重于发展满足不同功率谱掩模的脉冲发生器，例如FCC、欧洲和日本的掩模。本研究计划的中间目标是研究超宽频穿壁雷达的链路预算分析和使用超宽频雷达的材料特性。该研究计划的结果将是UWB收发器系统的通用实验室模型（在模块级别），以验证从数据通信到发现患者的重要活动（心跳和呼吸频率）的各种应用。这项研究将有助于加拿大电信和医疗行业在快速增长的超宽带技术市场中占据竞争优势。这项研究将通过衍生产品或技术许可产生收入。

Ultra wideband (UWB) is a new and emerging short-range device technology with potential benefits for wireless communications, radars, localization and security applications. UWB communication devices can be used in wirelessly distributed services such as phone, cable, and computer networking throughout a building or a home. UWB has potential in both home and business markets, based on its low cost as well as high-speed data transmissions capability, and could be well suited for various video distribution applications. UWB radars find its application as medical imaging radars and through-wall probing radars. Apart from these applications, UWB technology will find applications in various surveillance applications.  The primary objective of this research program is to develop new design guidelines for passive UWB components such as antennas, filters, hybrid couplers, etc. This research also focuses on the development of pulse generators to satisfy different power spectral masks, e.g., the FCC, European and Japanese masks. The intermediate objective of this research program is to study the link budget analysis for UWB through-wall radar and the characterization of materials using UWB radar. The outcome of this research program will be a generic laboratory model (at the module level) of UWB transceiver system to verify various applications ranging from data communications to finding vital activities (heart beat and breathing rate) of a patient.This research will assist the Canadian telecommunication and medical industries to seize competitive advantage in the fast growing market of UWB technology. This research will generate revenues through spin-offs or licensing of technology.
