摘要:Microwave non-destructive testing and evaluation (NDT&E) has tremendous potential for defect detection in metallic materials. In this paper: 1) An open-ended waveguide based scanning system operating in the X-band (8.2GHz to 12.4GHz) with a spatial-frequency feature extraction algorithm for defect detection at large lift-offs is presented; 2) A full mathematical derivation for modelling the spatial-frequency characteristics in the presence of defects and without defects is provided; 3) A spatial-frequency feature extraction algorithm using the NMF developed and investigated.
