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.
