Application of Swept Frequency Measurements to the Embedded Modulated Scatterer Technique

The embedded modulated scatterer technique has shown promise as a viable nondestructive inspection method for the evaluation of a variety of materials and composite structures. In order for the technique to be successfully applied, the scattered (reflected) response from the embedded probe must be separated from the reflections resulting from other targets. Therefore, swept-frequency measurements, in conjunction with using Fourier Transforms, are proposed as one such way to obtain an individual probe response. This investigation outlines the difficulties associated with the embedded modulated scatterer technique using a single frequency and presents the new method of incorporating swept frequency measurements to obtain a probe response separate from other reflected signals.
