Ground-Penetrating Radar for Archaeology (eBook, PDF)

• Format: PDF

Produktbeschreibung

Ground-penetrating radar is a near-surface geophysical technique that can provide three-dimensional maps and other images of buried archaeological features and associated stratigraphy in a precise way. This revised edition, by the expert in the field, provides the basics of the physics, chemistry, geology, and archaeology in a clear fashion, unburdened by complex equations or theory. Additions to the forth edition include: Updates to recent hardware and software advances in three-dimensional antenna array systems and antenna offset technology;Expanded data processing methods that explains how to get more from your raw data, with examples to show why this is necessary and the results obtained;Expanded examples from around the world and in various environmental settings that explains how non-traditional data analysis steps can provide clarity to results in ways that are not usually done with traditional.The reader will be able to understand how the latest equipment and software and the results of data collection and processing can be used effectively in a number of different settings. Both potential pitfalls and successes and the reasons for them are discussed. With over 100 images and important tables and graphs, this book is a useful reference in the field and for data processing in GPR.

Autorenporträt

Lawrence Conyers is the author of five books on GPR, and more than forty-five peer reviewed journal articles. He was one of the first to develop GPR techniques for both archaeology and geological applications starting in the late 1980s and has been on the forefront of using these methods to find, map and understand buried sites around the world. He was also instrumental in developing software for imaging the ground, with hundreds of software users around the world. His specialty is GPR, and recently the integration of GPR results with magnetic gradiometer data. He began his academic career at the University of Denver, Colorado in 1995, specializing in using geophysics for mapping buried archaeological sites. The last 25 years of his research has taken him to more than 65 countries around the world on all inhabited continents.
