Phase Coherence, Inc. — Department of Defense SBIR Phase I: There are small but significant electromagnetic fields associated with adversaries'op

Description

There are small but significant electromagnetic fields associated with adversaries'operations in the near-field, including electric generators, power distribution systems and underground power lines. By using our proposed coherent laser-based sensing techniques detections out to 10 km may be feasible. These fields typically oscillate at a known frequency, e.g., 60 Hz. There is also significant electric charge on natural dust particles in the atmosphere. As a result we expect significant vibratory motion of particles in the vicinity of the electromagnetic sources. By remotely measuring the vibration we can remotely measure the electromagnetic fields over an area.
