ABSTRACT:
A random signal flaw detection system is disclosed that provides enhanced system sensitivity and/or increased range capabilities as well as being capable of improved resolution where necessary or desired. The system includes a generator which produces random electrical signals which are converted at a transducer into ultrasound for transmission into a test object. The reflected signal is received at a transducer and converted to an electrical signal which is then correlated with a delayed sample of the transmitted signal with the output being indicative of the sensed flaws in the test object.
