About the Project
The interpretation of data from such microwave sensors still relies on human experience, which often makes it subjective and error-prone. Full waveform inversion (FWI) – which can produce high-resolution electromagnetic models – can greatly assist with solving this problem, but has yet to see widespread adoption. Key reasons for this are that: FWI requires an accurate forward solver that is able to model the complex environments that microwave sensors are used in; and FWI is incredibly computationally demanding requiring many forward simulations to converge to a solution. Recently, however, much progress has been made both on the capabilities and performance (through GPU execution) of the forward solver, as well as the use of machine learning. It has been demonstrated that deep neural networks can be trained to simulate data in the same way as a forward model, and execute using a fraction of computational resource.
The project will combine numerical modelling, using open source electromagnetic modelling software gprMax (http://www.gprmax.com), full waveform inversion, and machine learning. An inversion framework will be developed that is based on a machine learning approach, and will be applied to one or more of the aforementioned application areas. It is a highly multi-disciplinary area of research, involving civil engineering, electrical engineering, geophysics, and high-performance computing.
This project is supervised by Dr Craig Warren.
