Imaging the shape of buried objects represents a major challenge for a range of interests, a well-known example being the detection of artefacts in archaeology.  Among all the possible geophysical techniques, Ground Penetrating Radar (GPR) is certainly the best candidate, but its resolution is very much limited by the need to use low frequencies to overcome attenuation of the waves in the soil. However there is theoretical evidence that it may be possible to overcome the "wavelength limit" of resolution using new techniques known as "super resolution", so enabling much improved GPR images.  This project is investigating the potential to exploit these new ideas.
