Imaging of a reinforced wall. (a) Geometrical distribution of the steel bars inside the wall. (b) Time domain raw data. (c) Imaging result using the proposed algorithm, correct wall parameter, εb = 6. (d) Imaging result using the ray tracing-based back-projection algorithm, correct wall parameter, εb = 6. (e) Imaging result using the proposed algorithm, underestimated wall parameter, εb = 3. (f) Imaging result using the proposed algorithm, overestimated wall parameter, εb = 10.
