Description

The purpose of this paper is to describe an extension to an integrated model for assessing the performance of a given ultrasonic inspection system for detecting internal flaws. The integrated model is described in Fertig, Richardson, and Elsley (1984). The modified model incorporates the use of multiple waveform information obtained in a scanning mode. It is demonstrated that the proper use of this information can enhance the detectability of interior flaws. The next section describes the noise model for the scanning experiment. Section 3 develops an approximation to a decision theoretic solution to the detection problem and Section 4 provides a computer simulation.

Statistical Flaw Detection in a Scanning Mode
