Prof. Motoyuki Sato, Tohoku University, Japan
Biography:
Motoyuki Sato received the B.E., M.E degrees, and Dr. Eng. degree in information engineering from the Tohoku University, Sendai, Japan, in 1980, 1982 and 1985, respectively. Since 1997 he is a professor at Tohoku University and a distinguished professor of Tohoku University since 2007, and he was the Director of Center for Northeast Asian Studies, Tohoku University since 2009-2012. From 1988 to 1989, he was a visiting researcher at the Federal German Institute for Geoscience and Natural Resources (BGR) in Hannover, Germany. His current interests include transient electromagnetics and antennas, radar polarimetry, ground penetrating radar (GPR), borehole radar, electromagnetic induction sensing, interferometric and polarimetric SAR. He has conducted the development of GPR sensors for humanitarian demining, and his sensor ALIS which is a hand-held dual sensor, has detected more than 80 mines in mine fields in Cambodia since May 2009. He is a visiting Professor at Jilin University, China, Delft University of Technology, The Netherlands, and Mongolian University of Science and Technology. He was the technical chair of International conference on Ground Penetrating Radar, GPR96 held in Sendai, Japan and he served the general chair of IGARSS2011.
Title: Ground Penetrating Radar (GPR) / UWB radar: Fundamentals to applications
Abstract:
Ground Penetrating Radar (GPR) is one form of radar, which is used for subsurface sensing. It has been widely used for detection of buried utilities such as pipes and cables. This technique is also highly sensitive to water content in soil; therefore, GPR is very suitable for environment study, too. Recently, Ultra Wide Band (UWB) technology has gathered interest, however, its frequency bandwidth has been used in GPR for a long time, and we can find many similar aspects. Typical application of UWB radar is detection of objects in air, however, most of the fundamental signal acquisition and signal processing schemes are almost as same as that has been used in GPR.
In this tutorial course, we will introduce the fundamental principles of GPR and UWB radar technologies to potential users, students and researchers. The course will cover electromagnetic wave propagation and reflection in material, antennas for GPR, GPR system, GPR survey design, signal processing, and image reconstruction. Then we will introduce examples of applications of GPR and UWB radars, which include our recent activities for humanitarian demining by ALIS. GPR technology is closely related to Electromagnetic wave theory and signal processing technology. Therefore, I believe this course is also very useful for researchers and students who are familiar with electrical communications and signal processing theory.
