Air-coupled non-destructive evaluation technology for condition assessment of railroad ties
… sensed at the receiving end using an array of Micro-Electro Mechanical sensors (MEMs). The resulting wave field is visualized in time-space (t-x domain) and frequency-wavenumber domains (f-k domain) to derive parameters indicative of the extent of damage in crossties. A robust “wave front …
