Test and evaluation of the micro-observer sensor system for use as a seismic surveillance device in an integrated sensor network

Abstract

This thesis investigated the feasibility of deploying unattended seismic ground sensors in an operational environment to provide persistent surveillance and early warning detection capabilities. The system employed was the commercially available MicroObserver Sensor System. A robust testing and evaluation plan was created to measure the system's objective performance based on specific criteria. The tests focused on the capabilities of the sensor system across a broad range of deployment environments. Tests were conducted to determine probabilities of detection, battery life and operational effectiveness. Prediction models of the sensor system's ability to detect targets were also created to assist planners assess the utility of the MicroObserver Sensor System in specific operations. Although the sensing capabilities satisfied the established metrics, the sensor system possessed inherent limitations inhibiting its adequacy for use in many military operations. However, the sensor network would work well in many security applications where specific sensor system weaknesses could be anticipated and mitigated.
