The paper is focused on the design of a new reconfigurable tactical UWB impulse radio enabling indoor communication and localization for military application. The proposed system contains both a physical and a MAC (Medium Access Control) layer. It proposes to answer military needs for information sharing and for indoor localization of infantry. The physical layer is based on IR-UWB (Impulse Radio Ultra WideBand). Its goal is to ensure communication and distance evaluation between the transmitter and the receiver. IR-UWB is necessary for constraints such as low power consumption, reconfigurability, through the wall propagation, fine resolution localization, low probability of detection and interception. These advantages come from the use of a very large bandwidth with very short pulses.
