Ultra-wideband technology for defence applications

This paper deals with the use of ultra-wideband technology (restricted to impulse radio UWB) for military purpose related to radar, telecommunication or localisation. After defining what a UWB signal is, its physical features are described, as well as a few constraints relevant with the future systems. From this, some particular military applications are inferred and depicted thanks to the current work carried out at CELAR. Keeping in mind these potential applications, operational missions are presented, for which UWB technology may bring advantages. Finally, some prospects concerning studies at the DGA are considered.
