摘要：

Algorithm development work is described for the initial phase of a two-part task, where these algorithm upgrades improved existing material characterization-related data collection by culling ultrasonic signals for quality and designing a more noise-resistant time-of-flight estimate. This prepares the existing factory-installed ultrasonic signal analysis system for future data collection and algorithm training, yielding a more comprehensive, real-time material characterization capability within this manufacturing setting.
