Abstract :
The capabilities of microwave sub-surface imaging system for structural damage detection using cylindrical reflection tomography arrays are described. The analytical expressions of the bifocusing procedures are derived. Finally, reconstruction parameters such as resolution and intensity level are discussed and some images from simulations are also shown.
