Biography

Yaoguo Li received the B.A.Sc. degree from Wuhan College of Geology, Wuhan, China, in 1983 and Ph.D. degree from The University of British Columbia (UBC), Vancouver, BC, Canada, in 1992, both in geophysics.,From 1992 to 1999, he was with the UBC Geophysical Inversion Facility, first as a Postdoctoral Fellow and then as a Research Associate. He is currently an Associate Professor with the Department of Geophysics, Colorado School of Mines, Golden, CO, USA, where he directs the Center for Gravity, Electrical, and Magnetic Studies. His research interests include geophysical inverse theory; inversion of gravity, magnetic, and electromagnetic data; and their application to mineral and oil & gas exploration and production problems.(Based on document published on 3 November 2015).

Feasibility and Limitations of Void Detection Using Gravity Gradiometry

Jason R. McKenna;Hyoungrea Rim;Yaoguo Li

IEEE Transactions on Geoscience and Remote Sensing
Year: 2016 | Volume: 54, Issue: 2 | Journal Article |
Cited by: Papers (8)
Detecting and characterizing near-surface voids is a long-standing problem in near-surface geophysics primarily because of the low signal-to-noise ratio due to the typically small sizes of these targets. Anticipated advances in gravity gradiometry instrumentation and data acquisition may provide the improved resolution required to address these targets. In this paper, we investigate void detection...Show More

Enhancement of Magnetic Data by Stable Downward Continuation for UXO Application

Yaoguo Li;Sarah G. R. Devriese;Richard A. Krahenbuhl;Kristofer Davis

IEEE Transactions on Geoscience and Remote Sensing
Year: 2013 | Volume: 51, Issue: 6 | Journal Article |
Cited by: Papers (37)
The magnetic method has been proven to be a successful geophysical tool for the detection of unexploded ordnance (UXO). Aeromagnetic surveys are advantageous since they can acquire data over large areas. The downside is that magnetic anomalies due to multiple metallic targets can overlap significantly due to flight height restrictions. Such overlap combined with the acquisition noise may significa...Show More

Quantitative Analysis and Interpretation of Transient Electromagnetic Data via Principal Component Analysis

M. Andy Kass;Yaoguo Li

IEEE Transactions on Geoscience and Remote Sensing
Year: 2012 | Volume: 50, Issue: 5 | Journal Article |
Cited by: Papers (18)
Transient electromagnetic (TEM) data in applied geophysics are invariably contaminated by random and coherent noise associated with acquisition, geology, and the environment. Advanced unexploded ordnance (UXO) detection and discrimination using TEM data require the suppression of the random noise and reliable separation of UXO signal from other coherent signals. The random noise is usually easier ...Show More

Numerical Modeling of Higher Order Magnetic Moments in UXO Discrimination

Vinicio Sanchez;Yaoguo Li;Misac N. Nabighian;David L. Wright

IEEE Transactions on Geoscience and Remote Sensing
Year: 2008 | Volume: 46, Issue: 9 | Journal Article |
Cited by: Papers (32)
The surface magnetic anomaly observed in unexploded ordnance (UXO) clearance is mainly dipolar, and consequently, the dipole is the only magnetic moment regularly recovered in UXO discrimination. The dipole moment contains information about the intensity of magnetization but lacks information about the shape of the target. In contrast, higher order moments, such as quadrupole and octupole, encode ...Show More

Imaging Cargo Containers Using Gravity Gradiometry

Barry Kirkendall;Yaoguo Li;Douglas Oldenburg

IEEE Transactions on Geoscience and Remote Sensing
Year: 2007 | Volume: 45, Issue: 6 | Journal Article |
Identifying fissile materials inside cargo shipping containers is a current national security need. We propose using the geophysical technique of gravity gradiometry to image cargo shipping containers for the purpose of detecting high-density materials. We focus on developing the necessary numerical algorithms and carrying out feasibility studies without being concerned with engineering, instrumen...Show More
