Abstract
In ultrasound systems, the analysis of inherent signal-to-noise ratio (SNR) is one of the eternal topics. Desired signal improvements of approximately 10 times are theoretically possible for ultrasonic testing (UT) using coded excitation. When applying the coded excitation into the ultrasound pulse-echo system, code selection is important as the limited time duration of the transmission pulse. Any selected code sequences can hardly get a good auto-correlation property. In earlier reports, a technique called Truncated Long Code (TLC) was proposed for dynamic signal detection [1–3]. Good auto-correlation property has been acquired as the parameter estimation time window can be much longer than the single pulse duration. In this report, we use the same approach to form a multi-segment coding scheme to detect the stationary objects in ultrasound pulse-echo system. The importance of this study are to confirm the efficacy of this new scheme and try to find possible uses in biomedical and industrial applications as well.
