... Over the past 3 years SPH Engineering has gained a lot of practical experience in using ground penetrating radars (GPR) on drones for various experiments and real missions. Starting from gas pipeline inspections in Latvia to inspecting archeological sites in Peru and searching and successfully...

... Lightweight ground penetrating radar (GPR) systems mounted on multirotor drones is a trend that has risen in popularity over the past few years. Efforts of some manufacturers and systems integrators who promote airborne GPR systems for a variety of applications have been the drivers behind...

... ABSTRACT Applications of geophysical tools have always been an integral practice in near-surface characterization. We present an effective combination of ground penetrating radar (GPR) and magnetic gradiometry to detect buried objects within ~1 m of the surface. These objects are comprised...

... ABSTRACT Electrical methods are proven tools for successfully imaging the subsurface (Jol, 2008; Knight, 2001). Ground penetrating radar (GPR) is sensitive to electrical permittivity through reflectivity and electrical conductivity through attenuation. Electrical resistivity tomography (ER...

... ABSTRACT Ground-penetrating radar (GPR) surveys were conducted to identify unmarked graves in active cemeteries located in two small towns in the mountains of Idaho, USA. The cemeteries have been active since the mid 19 to early 20 centuries. GPR results correlated well with known grave sites...

... ABSTRACT This document presents a scale laboratory test where a 2.0 GHz ground-penetrating radar (GPR) is used to assess a controlled fuel oil injection in a shallow sand tank setup. The test analyzes several scenarios involving different levels of water saturation and fuel oil contamination...

... ABSTRACT We use ground-penetrating radar (GPR), terrestrial laser scanning (TLS), cemetery records, and oral histories to locate and characterize unmarked burials at the Mueschke Cemetery in Houston, Texas. Concrete burials were used after 1940 while wooden burials were common before 1940. We...

... magnetic survey, a self-potential (SP) survey, electrical resistivity tomography imaging, and ground penetrating radar (GPR). A survey area measuring 85 meters east to west and 120 meters south to north completely contained the grave mounds. The survey grid was 5 meters spacing in the east-west direction...

... Summary A series of geophysical surveys using ground-penetrating radar (GPR) and electromagnetic induction (EM) were conducted at Padre Island National Seashore (PAIS), Texas to characterize barrier island transgression at a range of spatial and temporal scales. The first study (June, 2010...

... Summary A constant rate infiltration experiment was conducted in a homogeneous sand tank and monitored with time-lapse multi-channel ground-penetrating radar (GPR) to observe patterns associated with wetting fronts and dynamic hydrologic conditions. The tank measures 4 m x 4 m x 2 m...

..., and the continuing need to improve detection and to map not just locate buried utilities has led to implementations of technologies such as GPR. GPR has been developed into a tool with worldwide use for locating and mapping utilities. Like EM locators, GPR has limitations. High conductivity soils such as clays...

Young, Roger M Slatt. University of Oklahoma Summary The Rattlesnake Ridge is an outcrop from the Lewis Shale, Wyoming...

.... Groundpenetrating radar (GPR) is a tool that can potentially provide laterally continuous measurements. Previous studies have shown that measurements of GPR velocity can provide accurate estimates of SWE in dry snow. However, introduction of liquid water into the snowpack results in a 3- phase system that cannot...

... ABSTRACT Ground penetrating radar (GPR, ) has proven to be a rapid and inexpensive geophysical tool for the exploration of near surface gem-bearing pegmatites. Reasonable images and reliable interpretations have made this technique acceptable to miners for assisting in mine development. We...
