Abstract

In this study, a commercial 20-MHz 64-element 1 mm-pitch flexible linear array, developed by Novosound Ltd, was evaluated using two different coded excitation techniques to enhance the signal-to-noise ratio and operability on flat and complex-geometry components. Chirp and Golay coded excitation techniques were employed with an arbitrary waveform generation tool to excite the array. A pulse compression technique consisting of a matched filter was implemented, weighted by a Chebyshev window for Chirp excitation.
