Guidance on environmental vulnerabilities of unattended ground sensors

Operational guidance on reliability as a function of site conditions is essential to unattended ground sensors (UGS) effectiveness. For physical security/force protection sensor systems, the Weather Vulnerability Assessment Tool (WVAT) will fill this need. WVAT is a computer application that will warn of situations in which the likelihood of detecting an intruder falls below a specified probability of detection (Pd). Both Pd and the likelihood of nuisance alarms are predicted for diurnal and seasonal variability in weather, state of the ground, and ground cover. A follow-on computer applications, the Force Protection Sensor Selector, will guide the selection of sensor systems for deployment as a site, based on its prediction of weather-induced variation in site conditions.
