2.  Introduction  Challenges  Applications Outline

3.  The first Ground Penetrating Radar (GPR) was developed by Walter Stern and used to survey a glacier in Austria in 1929.  After WWII, GPR was developed for military application such as locating tunnels in the DMZ between North and South Korea.  GPR first became commercially available in 1972.  The first affordable GPR system was sold in 1985 and first comprehensive reference books was written in the 1990s. Introduction

4.  Soils are 3D natural bodies consisting of unconsolidated mineral and organic materials that form a continuous blanket over most of the earth’s land surface.  At all scales of measurements, soils are exceedingly complex and variable in biological, chemical, physical, mineralogical, and electromagnetic properties. These properties will influence the propagation velocity, attenuation, and penetration depth of electromagnetic energy, and the effectiveness of GPR. Challenges
