- Abstract
The article presents the results of applying the signal time reversal method in the ultrasound (~130 kHz) under strong spot heating conditions (>250°С) and deformation of the investigated sample—a steel plate. It is shown that the distortions of the time-reversed signal during propagation, caused by changes in the sample properties, can be significantly reduced by reducing the duration of the processed signals and by using several receivers.
