Passive, Acoustic, Seismic and Electromagnetic Monitoring (PASEM)

This program developed validated, phenomenological models for a range of UGF signatures: acoustic, seismic, electromagnetic (EM), chemical, multi/hyperspectral, and gravity/gravity gradient. These models enabled the evaluation of multiple sensor/targeting concepts, and defined performance requirements for highly sensitive, advanced sensors. The CUGF Unattended Ground Sensor System (CUGSS) functional prototype ground sensor network meeting these requirements was demonstrated using multiple, networked ground nodes of multi-phenomenological sensors (EM, acoustic, seismic) for successful UGF monitoring and target characterization. Innovative technologies such as robust geophone coupling techniques, miniaturized E- and B-field sensors, low profile antennas for NLOS communications, and advanced signal processing have also been demonstrated. The CUGSS sensors are currently being used in additional data collections and user testing to determine the final output product and deployability and operability goals for a transitioned system based on this technology.
