Ultrasonic Flaw Detection and Imaging through Reverberant Layers via Subspace Analysis and Projection
Figure 7
Reverberation removal in a high clutter area. (a) Simulated flaw echo and its multipaths received by the 4th transducer shown in Figure 1. (b) The flaw echo and its multipaths added to the reverberation measurement. The flaw echoes are completely buried in reverberation. (c) Reverberation removal via subspace projection.
