Abstract
A new method for improving resolution without increasing operating frequency is proposed. This bistatic version of the holographic technique involves illuminating the buried services from a source antenna placed on, or implanted slightly below the interface. Resolution is improved by scanning in the surface wave region close to the interface. Computer simulations are used to predict the scattered field in sandy soils with 10 and 20% gravimetric moisture content at 300MHz. Some experimental simulations at 500MHz in tap water at 15°C illustrate the improvement in resolution gained by scanning in close proximity to the surface.
