Majority of the unattended ground sensors (UGS) use both acoustic and seismic sensors to detect various targets, namely, people, vehicles, etc. The UGS once deployed should for several months before changing the batteries. This implies use of fewer sensors may result in longer UGS life. Towards this goal, we are exploring the possibility of buried microphone to perform the task of both seismic and microphone functions. In this paper, we analyze the performance of a buried microphone to detect voice and footsteps.
