Advanced Concepts in Structural Materials and Testing. Part I. The Application of Random Signal Correlation Techniques to Ultrasonic Flaw Detection in Solids

Abstract

The work performed under this program can be subdivided into two areas. The first deals with the application of random signal correlation techniques to ultrasonic flaw detection in solids and the second deals with the development of modulated microstructure heat treatable steel. A random signal ultrasonic flaw detection system, has been constructed and operated. It has been demonstrated that the resolution of the system is independent of the length of the transmitted signal. This indicates that a much lower peak to average power ratio can be used than is possible with pulse-echo systems.
