Development of an Advanced Wideband Airborne Electromagnetic
Sensor

Abstract:

This proposal sets forth a feasibility study for an advanced,
wideband, airborne electromagnetic (AEM) sensor with
environmental investigation applications. The goal is to validate
and demonstrate the feasibilty of an innovative design for an
aircraft-towed electromagnetic sensor capable of high-speed
surveying and imaging of subsurface targets and conditions of
environmental interest. The unique, monostatic coil system
design, combined with full, digital computer control, will
provide wider bandwidth and higher signal-to-noise ratios than
any system to date. This high quality data will make possible
inversion analyses which have never before been possible. As part
of this program, a hand-held unit will also be developed which
will be particularly applicable to small target areas. Possible
applications include subsurface environmental assessments,
shallow marine investigations, and soil studies.
