Borehole / Ground penetrating radar research opportunities

[behold]

Hi Members

I am preparing to do a presentation on possible research opportunities in ground penetrating radar before an Industry and academic audience. Anyone with information as to what is lacking or needs improvement in current BH or GPR research in the context of Data analysis (processing and interpretation)?

you mean general Geotechnical exploration tools?

Research opportunities in gpr/borehole radar

Yes, Geotechnical exploration is part of applications of ground penetrating radar and/or borehole radar- This is actaully a specialised geophysics technique used for the following:

Subsurface surveys eg finding buried landmines, minerals, cavities, underground water, soil property investigations, even geotechnical investigations such as bridge decks, tunnel investigations, concrete integrity assessment

GPR/Radar based on timing and imaging electromagnetic waves that reflect on interfaces or objects with a change of electrical properties compared to surrounding medium. There are several other techniques eg those that use artificial shock/sesmic waves
to explore the Earth subsurface

Thanks

I am not familiar with this geophysics procedure. In general, in large scale projects it is preferred digging holes, method with thin walled tubes, rotatory methods for rocks, and the like (in-situ methods) over geophysical methods (sismic, electric resistivity, magnetic and/or gravimetric).

I am not saying geophysical methods are not used. They are, mainly for preliminary research, but the information they provide is not seen as reliable as others and is never enough for a project (such as foundation design).

Hey again, i looked up in google and i found this paper on the topic. It highlights the main problems with geophysical methods.
