Paper Abstract

The cost of an unattended ground sensor system is based on two factors: the number of sensor nodes used and, the complexity of each sensor/communications node. The tracking accuracy of the sensor network is a trade off between the density of the network and the accuracy with which the sensor nodes can determine the position or bearing of the target. Assuming acoustic sensors, the errors reduce, primarily, to timing errors, within each of the sensor nodes. Therefore that understanding the timing errors within a network of acoustic nodes is a factor in determining system cost for a given level of information fidelity. This paper explores the error mechanisms within and without each of the sensor nodes thus identifying the critical sub systems where engineering effort would be most effectively directed.
