Coal Seam Thickness Estimation Using GPR and Higher Order Statistics – The Near-Surface Case
Strange, Andrew D., Chandran, Vinod, & Ralston, Jonathon (2005) Coal Seam Thickness Estimation Using GPR and Higher Order Statistics – The Near-Surface Case. In Eighth International Symposium on Signal Processing and Its Applications, August 28-31, 2005, Sydney, Australia.
A novel pattern recognition-based approach to detect near-surface interfaces using ground penetrating radar (GPR) has been reported in . The approach was used to successfully detect interfaces within 5 cm of the ground surface. This technique has been adapted for the important task of layer thickness estimation in the near-surface range. This is inherently a difficult problem to solve in practice because the radar echo is often dominated by unwanted components such as antenna crosstalk and ring-down, ground reflection effects and clutter. Features derived from the bispectrum and a nearest-neighbour classifier have been utilized for this processing task. It is shown that unlike traditional second order correlation based methods such as matched filtering which can fail in known conditions, layer thickness estimation using this approach can be reliably extended to the near-surface region.

Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
