Description

Electric field sensing can provide important signatures for revealing the operations of adversaries that involve electrical power transmission and use.A novel approach to the remote sensing of associated electric fields is proposed that can determine field intensities similar to those found near common electrical hardware and naturally occurring electric fields.Through a unique infrared Lidar (Light Detection and Ranging) system design, the electric field can be indirectly detected through its impact on the properties of the surrounding air.Operating at eye-safe laser wavelengths, such a system can have an effective sensing range exceeding 10 km.The Phase I effort has experimentally confirmed the detectability of electric fields of the magnitude and frequency associated with common power lines in a laboratory test system, and provided an initial design concept that can implement this standoff detection method.The Phase II program will develop and test a system capable of remote detection and 3D imaging approaching distances as large as 10 km.It will also address the potential for improved sensitivity so as to assist in the location of hidden facilities that emit electric fields.The ultimate goal is to develop an airborne system capable of detecting facilities in denied access areas.
