The objective of this project was to develop
a new subsurface radar system for the non-destructive testing (NDT)
of buildings and other constructions, enabling information to be
gathered about their nature and condition. The new equipment transmits
pulses of electro-magnetic energy, generally in microwave frequencies,
and receives reflections from interfaces where there is a discreet
change in material properties.
Partners also investigated the dielectric properties
of brick, stonework, concretes and aggregates, as well as more complex
materials, configurations and qualities, including multi-layer reinforcement,
moisture, porosity and salinity. Current dielectric models were
also improved by studying the responses of a number of radar systems
to construction and material features incorporated into physical
models, both in the laboratory and in the field.
The potential economic benefits include
the direct sale of radar testing services and equipment, as well
as improvements in European standards conformity and damage prevention.
