f Radar techniques for the evaluation of masonry structures

Civil engineers have a need to evaluate the condition of masonry structures such as bridges and tunnels in order to classify the condition of the structure . Impulse radar techniques have been used in the past, but interpretation of the data has been difficult as the radar data does not necessarily correspond with the geometrical structure . British Rail Research commissioned ERA Technology, over several years, to carry out a detailed investigation of the correlation between the radar image and the physical structure, in order to improve the clarity of the radar image .
