During recent years, low power ultra wideband (UWB) sensors have become more and more interesting for a great deal of civil, industrial and military applications. UWB sensors may be used for imaging and localization systems, ground–penetrating radars, non-destructive testing and radio channel investigation (e.g. channel sounding) and many more. This has resulted in a diversity of requirements concerning the measurement system – touching both its electronics and signal processing. The article deals with flexible ultra-wideband electronics whose behaviour can be adapted to different parameters. This concerns for example the bandwidth, the operational frequency band, the measurement speed, the system costs, the number of channels and others

The working principle is based on a special type of very wideband Pseudo-Random Code– the M-Sequence. The mother device which is working in the baseband provides a bandwidth up to 7 GHz (typically 5 GHz), this is explained in detail in. Here, only a short summary will be given as a starting point for some modified approaches which are aimed to allow very wideband operation at an arbitrary frequency band or to increase the system flexibility by replacing RF-filters by digital ones.
