This paper is concerned with the development of a new system identification based approach for pulsed eddy current non-destructive evaluation. The new approach regards the relationship between the eddy current probe excitation and sensor response as a system, uses the system identification techniques to establish a transfer function model for the system from the excitation and response data, and extracts the features of inspected structures from the identified transfer function model parameters for non-destructive evaluations. The use of the new approach in experimental studies verifies its effectiveness and demonstrates its potential in engineering applications. © 2007 IOP Publishing Ltd.
