Ultra wideband (UWB) is a new and emerging short range device technology with potential benefits for wireless communications, radars, localization and security applications. UWB has potential in both home and business markets, based on its low cost as well as high speed data transmission capability, and is well suited for various high resolution video distribution applications. UWB radars find applications in medical imaging, target localization, fluid level measurement on transport vehicles, and through-wall probing. Apart from these applications, UWB technology will find applications in various surveillance applications. UWB systems are characterized by a wide system bandwidth and a low radiated power spectral density. It operates by exchange of short electromagnetic pulses between transmitter and receiver. Therefore it is very important to understand the pulse transmission, propagation and reception by UWB terminals for optimal system design.

超宽带（UWB）是一种新兴的短距离设备技术，在无线通信、雷达、定位和安全应用方面具有潜在的优势。UWB在家庭和商业市场都具有潜力，基于其低成本以及高速数据传输能力，并且非常适合于各种高分辨率视频分发应用。UWB雷达在医学成像、目标定位、运输车辆上的液位测量和穿墙探测中得到应用。除了这些应用之外，UWB技术还将在各种监控应用中得到应用。UWB系统的特征在于宽的系统带宽和低的辐射功率谱密度。它通过在发射器和接收器之间交换短电磁脉冲来工作。因此，了解超宽带终端的脉冲发射、传播和接收特性对于优化系统设计是非常重要的。
