Ultrawideband systems-features and ways of development

Consideration is given to the main specific features of ultrawideband (UWB) systems and possibilities of these systems to increase essentially the information performance of radars and communication. The problem of particular interest is the difference in constructions between UWB and conventional radar systems operating in a narrow frequency band. The difficulties caused by these differences when constructing UWB systems are determined. Also discussed are the ways to counter these difficulties, which makes it possible to expand the UWB radar application area and realize the advantage over conventional radar systems.
