Electromagnetic sensing technologies, such as Ground Penetrating Radar (GPR), are critical tools to allow us to evaluate the condition of surface and sub-surface infrastructure. The cost to the UK of inadequate infrastructure is estimated to be £2M per day, with 50% of our annual construction budget spent on maintenance and repair. GPR is used for a wide variety of infrastructure and geophysical investigation, including: assessment of bridges, roads, and railways; location of buried utilities; ice profiling and glaciology; and groundwater and soil condition monitoring.
This project will develop the concept of wide angle reflection and refraction (WARR) data acquisition for GPR. WARR surveying methods have existed since the inception of GPR but have had little adoption. This is because, unlike seismic systems, commercial GPR with multiple concurrent data acquisition receivers have not existed. Multiple offset GPR data had to be acquired using a single transmitting and receiving antenna pair moved to the desired offset sequentially. However with recent advances in GPR timing and control technology, modern instrumentation with multiple concurrent sampling receivers now provides the possibility of continuous, rapid acquisition of WARR data. Two-dimensional reflection surveys can now rapidly yield a multi-offset sounding at each recording station, providing WARR profiling at the same speed as a standard, single fold GPR sounding.
The project will combine numerical modelling, using open source electromagnetic modelling software gprMax (http://www.gprmax.com), development of data and image processing algorithms, as well as experimental work with an industrial partner. It is a highly multi-disciplinary area of research. Applicants with skills in geophysics or civil engineering are encouraged to apply, and experience of computing/programming is also desirable.
The project has industrial support from Sensors and Software Inc. (Canada) (http://www.sensoft.ca), who are a leading worldwide provider of sub-surface imaging solutions. There will be an opportunity for the student to spend a period of time working at Sensors and
Software’s base in Canada. The work also forms collaborations with the University of Edinburgh
(UK), and Aristotle University of Thessaloniki (Greece).
