T
he development of atomic
dielectric resonance (ADR)
by Dr G. Colin Stove was
inspired by his experiences
of working with synthetic aperture
radar (SAR) sensors, from both
satellites (ERS1 and RADARSAT) and
from the Space Shuttle Imaging
Radar-B experiment in the early 1980s,
as well as his work with conventional
ground penetrating radar (GPR)
systems.

ADR was developed as an
improvement over SAR and GPR to
achieve deeper penetration of the earth’s
subsurface through the creation and use
of a novel type of coherent beam. ADR is
used as a geophysical technique and
precision instrument, which provides
accurate geological recognition of rock layers
and identifies rock types. This is achieved via
transmission through the rock medium, as well as
reflection from each subsurface rock layer.
The aim of this paper is to report on surveys of the
subsurface earth penetration capabilities of a new
spectrometer, as well as its ability to recognise thin coal
layers and many sedimentary, igneous and metamorphic rock
types in real-world conditions.
Methodology
ADR is a patented investigative technique that involves the measurement and
interpretation of resonant energy responses of natural or synthetic materials.

These
materials interact with pulsed electromagnetic radio waves or microwaves from
materials that permit the applied energy to pass through the material.
Gordon Stove, Adrok Ltd, UK,
discusses atomic dielectric
resonance technology,
which has the potential
to transform coal
exploration practices.
