Measurement of Acoustic Emission Signals Using Doppler Radar

Specialist nondestructive testing (NDT) know the method of acoustic emission. One of its advantages is high reliability of obtained results. Shows the sources of emissions do not doubt the presence of identified dangerous areas. The disadvantages of this method are the need for prior mechanical loading and the use of contact piezoelectric transducers. These limitations can be eliminated by applying the "Gorbunov"effect, discovered by the authors. Its essence is the abnormal interaction of the elastic waves of ultrasound with electron gas.
