Swept-Frequency eddy current excitation for TMR array sensor and Pulse-Compression: Feasibility study and quantitative comparison of time and frequency domains processing
Measurement(2022)
摘要
•Chirp signal has been used in combination with TMRs array eddy current probe.•Time analysis has been enabled via pulse-compression algorithm.•Quantitative/qualitative comparison of frequency and time domains analyses is shown.•Benefits of the proposed approach are discussed.
