A Controlled-Site Comparison of Microwave Tomography and Time-Reversal Imaging Techniques for GPR Surveys

Abstract

This paper provides a comparative study between microwave tomography and synthetic time-reversal imaging techniques as applied to ground penetrating radar (GPR) surveys. The comparison is carried out by processing experimental data collected at a controlled test site, with different types of buried targets at given subsurface depths and representative soil conditions. It is shown that the two techniques allow us to obtain complementary information about position, depth and size of the targets from a single GPR survey.

Existing and Emerging Breast Cancer Detection Technologies and Its Challenges: A Review

“…Microwave Tomography (MT) is an emerging biomedical imaging technique to determine the dielectric characteristics of the tissue under investigation using the inverse scattering approach [73,74]. MT is extensively used in medical for non-invasive biological imaging.…”

IAG/USP Test Site: A Near Surface Geophysics Teaching and Research Laboratory

“…With the installation of the test site of the IAG/USP, different geophysical methods of near surface investigation were evaluated for performance and reliability when applied to urban problems, aiming at mapping subsurface interference, studies of environmental contamination and in archaeological research. The results of many of these works are published in the literature, such as: Porsaniet al (2004, 2006, 2010, 2017, 2018);Rodrigues and Porsani (2006);Porsani and Sauck (2007);Santos and Porsani (2011);Santos et al (2014Santos et al ( , 2018;Poluha et al (2017); among others.…”
