A fiber-distributed multistatic ultra-wideband radar
2015 14th International Conference on Optical Communications and Networks (ICOCN), 2015A fiber-distributed multistatic ultra-wideband (UWB) radar is proposed and demonstrated. The proposed radar includes a central office (CO), two transmitters and a receiver which are connected by optical fibers. The UWB pulses generated by the two transmitters are designed to have opposite polarities using the complementary transmission and reflection ...

Ultra-wideband radar-potential and limitations
1991 IEEE MTT-S International Microwave Symposium Digest, 2002Some of the more obvious uses of ultrawideband (UWB) radar are discussed, together with some of the problems (arising from limited source capabilities) in implementing adequate designs. It is pointed out that the primary limitation on such systems is the lack of peak output power.

Ultra-wideband radar based on COTS components
2019 Signal Processing Symposium (SPSympo), 2019This paper presents some issues of usage of mini vector network analyzer as ground penetrating radar. The main properties of the system and key requirements for ground penetrating radars are briefly discussed. Preliminary results of building floor scanning using the system are described as well.

New practical application of ultra-wideband radars
2007 European Radar Conference, 2007The possibility of ultra-wideband (UWB) radar use in various fields for remote measuring of the object's motion at short distance is considered. As an illustration UWB radar in medicine for remote measuring of patient's heart activity and respiration is shown. The measuring method is described and practical results of tests are cited.

Ultra-Wideband Principles for Surface Penetrating Radar
2005SPRs will achieve wide industrial employment if they succeed in offering adapted solutions for a specific class of tasks. These solutions will be based on sophisticated methods of digital data processing which require stable, high quality data, increasingly gathered by antenna arrays. The future challenge on RF-electronics is to meet these requirements.

A Low Power, Ultra-Wideband Radar Testbed
2005The availability of custom timer and correlator chips has enabled the design and development of a general purpose UWB research instrument by Time Domain Corporation. One configuration of this tool serves as a basic UWB Radar Testbed suitable for research on antennas and algorithms aimed at specific applications of UWB radar. The system includes the UWB
