Wireless Seismic/Acoustic Sensor Network for Ordna

Low-order detonations and unexploded ordnance (UXO) present an extremely difficult and expensive problem for DoD range managers. Near-real-time detection, location, and characterization of ordnance is important so that the number of rounds fired, impact time, location, and level of detonation can be provided for addressing singular low order or UXO events and for devising fiscally optimal cleanup schedules and management criteria. We propose to address this problem by a combined wireless seismic and acoustic sensor array network approach. By detecting seismic and airborne acoustic waves generated by the ordnance impact, the location, level of detonation as well as classification of the dud can be achieved. Our approach will be very useful for both military and civilian applications such as range management, explosion detection and seismography of earthquake etc.
