M-sequence ultra-wideband-radar: state of development and applications

The UWB approach is a promising and challenging technique for a great deal of sensor tasks for volume applications with economical and social impact. Impulse and swept sine waves are the classical methods to cover a wide spectral band. The M-sequence technique joins the merits of both principles without their drawbacks. The M-sequence technique provides stable UWB-data at reasonable costs and device dimensions due to its simplicity and the absence of bulky off-chip components which are amenable to monolithic integration.
