Evaluation of the Reconfiguration of the Data Acquisition System for 3D USCT

Complete processing chain of the adapted matched filtering [19] as implemented on the computing FPGAs. Firstly, we correlated the raw A-Scan with the matched filter signal (CorrMF). Then, we generated the absolute signal envelope (EnvGen) and in the following reduced it to its local maxima (PeakDet). Finally, the intermediate signal is convoluted with an optimal pulse for reflectivity imaging (ConvOP).
