Titel
New approach for location of continuously emitting acoustic emission sources by phase-controlled probe arrays
Abstract
A new method for localization a continuous AE source is described. This method bases on the phased array technique: The signals of several sensors are delayed and summed up. The sum signal reaches a maximum, if the delay times are equal to the time of flight differences from the source to the single sensors of the array. First results of localizing an artificial continuous noise source by a phased array probe are presented. (IZFP)
