Classification of MEC with the ALLTEM at Camp Stanley, Texas

Autor: Theodore H. Asch, David V. Smith, Craig W. Moulton

Publikováno v: SEG Technical Program Expanded Abstracts 2011.

The ALLTEM is a multi-axis electromagnetic induction system designed for unexploded ordnance (UXO) applications. It uses a continuous triangle-wave excitation and provides good late-time signal-to-noise ratio (SNR) especially for ferrous targets. Mul

An Algorithm for Waveform Inversion of Crosswell Radar Data

Autor: Jeffrey E. Lucius, Aldo T. Mazzella, Karl J. Ellefsen, Craig W. Moulton

Publikováno v: Symposium on the Application of Geophysics to Engineering and Environmental Problems 2007.

An algorithm for waveform inversion of crosswell radar data has been developed and implemented. The algorithm is based on an objective function that has two terms: One term measures the misfit between the calculated data and the observed data, both o

ALLTEM UXO Detection Sensitivity and Inversions for Target Parameters from Yuma Proving Ground Test Data

Autor: Charles P. Oden, Misac N. Nabighian, Yaoguo Li, David L. Wright, Theodore H. Asch, Craig W. Moulton, Philip J. Brown

Publikováno v: Symposium on the Application of Geophysics to Engineering and Environmental Problems 2007.

ALLTEM is a multi-axis electromagnetic induction system designed for unexploded ordnance (UXO) applications. It uses a continuous triangle-wave excitation and thus measures target step response rather than the more common impulse response. In May, 20

Improving Ground Penetrating Radar Imaging in High Loss Environments by Coordinated System Development, Data Processing, Numerical Modeling, and Visualization methods with Applications to Site Characterization

Autor: Michael H. Powers, David L. Wright, Craig W. Moulton, Gary R. Olhoeft, Charles P. Oden

The Department of Energy has identified the location and characterization of subsurface contaminants and the charcterization of the subsurface as a priority need. Many DOE facilities are in need of subsurface imaging in the vadose and saturated zones

ALLTEM FOR UXO APPLICATIONS – FIRST FIELD TESTS

Autor: David L. Wright, S. Raymond Hutton, Philip J. Brown, Craig W. Moulton, Theodore H. Asch

Publikováno v: 19th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems.

The ALLTEM system is a multi-polarization electromagnetic induction (EMI) system that uses a continuous triangle-wave excitation to drive each of three orthogonal (Hx, Hy, and Hz axes) transmitting coils. Received data are recorded on multiple simult
