Abstract
Signal-to-noise ratio and image resolution in an ultrasonic imaging system are compared for four kinds of excitation signals, namely, a single pulse, an unmodulated pseudo-random code, a modulated pseudorandom code and a deconvolved pseudo-random code, all for a given length and amplitude. It was predicted and found from measurements that the best S/N and resolution are obtainable with the deconvolved pseudorandom code.Keywords
