Spectral-Based Volume Sensor Prototype, Post-VS4 Test Series Algorithm Development

摘要

A retrospective analysis was undertaken to better understand the performance trade-offs involved in reducing the sensor count in the Spectral Based Volume Sensor Component Prototype developed as part of the Advanced Volume Sensor Project. Using a portion of the Volume Sensor Test Series 4 (VS4) data, superior performance was retrospectively demonstrated for several potential new configurations than was originally observed during the live VS4 demonstration. Additionally, it was possible to maintain a large fraction of the performance while utilizing fewer sensor elements than the original SBVS Component Prototype configuration. On the basis of these analyses, the current recommendation for the SBVS Component in the All-in-One VSP being developed by Vibro-Meter, Inc. (VMI) currently under ONR sponsorship is either a UV/IR or a NIR/UV/IR configuration, depeding on the data fusion systems tolerance for increased probability of false alarms with increased probability of detection.
