It's been 20 years since the opening of the new phenomenon of ultrasonic treatment on defects in the metal, which ingibiruetsa Doppler radar. The former results from the application of radar to monitor defects limited to surface discontinuities under the paint layer, other dielectric coatings. A new direction of remote detection of metal defects (cracks, metal stratification at a depth of several tens of centimeters) by Doppler radar of 30-40GHz frequency is now possible. Developed, tested sensor contactless indexing of acts of acoustic emission. A device for indicating defects that could previously be detected only by contact sensors based on piezoelectrics was tested. The paper deals with the causes of previous failures, low sensitivity of radars with their direct p. the possibilities of increasing the sensitivity due to the joint use of ultrasound and microwave radiation are Shown. The obtained results require a revision of the capabilities of the known ultrasonic flaw detectors of active and passive principle of action.
