Networked Sensors in Support of the NATO TG-25 Field Test Experiment

摘要

A field test experiment sponsored by the NATO Task Group (TG-25) was conducted in France in October 2002 to demonstrate acoustic and seismic unattended ground sensor (UGS) technology. Participants from member nations were afforded the opportunity to test and benchmark the performance of various sensor systems and share performance data in a collaborative networking environment. The ARMY Acoustic Center of Excellence (ACOE) deployed three sensor platforms in support of the test; a Hand Emplaced (HE02) acoustic/seismic sensor system developed by SenTech Corporation, an in-house developed acoustic data acquisition system, and a meteorological data collection node developed by Penn State University. In this paper we describe the detection, direction finding and target counting performance of the multi-sensor suite against multiple target scenarios that consisted of various heavy, light, wheeled and tracked vehicles. The results are based on report messages that were archived via a wireless Ethernet interface and TCP/IP network system called "SPIDER" that provided real-time visualization of sensor performance and managed the collection of UGS output data at a centralized server location.
