Application of ultra wideband (UWB) technology to an unattended ground sensor (UGS) network provides unique capabilities for capacity, covert operation, and location awareness. These features make this RF technology attractive for demanding military usage scenarios. Coupled with UWB's unique capabilities comes unique challenges when applied to autonomous, self-forming, and battery powered networks. In this paper we discuss essential design tradeoffs necessary to incorporate a UWB waveform into an ad hoc network of sensors. Background UWB information is provided followed by brief analysis of key range, data rate, LPI/LPD, interference rejection, synchronization, and location performance requirements. The paper concludes with system recommendations for application of the technology
