Electromagnetics
Detection and Mapping of Underground Structures
- Electromagnetic measurements can use both active and passive techniques.
- For passive measurements, the sources are: earth’s magnetic field (0 Hz); fluctuations in earth’s field (> 0 Hz); controlled sources (HAARP; > 0 Hz to 1 KHz, Wisconsin Facility); VLF Stations (> 10’s of KHz); sources associated with targets.
- For active measurements, the sources could be airborne, on the surface of the earth, or buried.
- Detection and mapping for each of these techniques can be performed using electromagnetic sensors.
- Numerical modeling using FEM can be performed to provide unambiguous answers to the: range of measurements, depth of target, stand-off distance, mapping accuracies, effects of different ground, effects of different frequencies and effects of different sources.
- CRS has unique modeling capabilities to provide these answers
