Abstract
Accurate detection of rebar location using Ground Penetrating Radar (GPR) proves to be very useful in assessing roadway/bridge deck concrete structure. Due to large signal processing resource needed to locate and image rebar on a whole road structure, more efficient signal processing method is needed. This paper proposes to combine two-dimensional (2D) entropy algorithm to narrow down the scope of interested data from large radar data set and Short Time Fourier Transform (STFT) algorithm to perform further feature characterization. To validate the analysis, experiments with different rebar setups are conducted.
