Ultrasonic Flaw Detection and Imaging through Reverberant Layers via Subspace Analysis and Projection
Figure 2
Comparison of reverberation removal techniques. (a) Simulated flaw echo and its multipaths measured through the layer. (b) Flaw echoes added to a real reverberation measurement. (c) Reverberation removal via subspace projection. (d) Reverberation removal via background subtraction. (e) Reverberation removal via predictive deconvolution.
