Small-Angle Acoustic Tomography under Shadow Testing with Antenna Arrays
Source abstract
Abstract
Results of the experimental studies of an acoustic tract by the shadow testing method are provided. An inhomogeneous distribution of acoustic rays is revealed within the testing zone. The principle of producing a tomogram under small–angle probing is demonstrated. As a result of studying the error in determining the coordinates of flaws in different parts of the testing zone, it has been established that the least error corresponds to the flaw position at the center of the testing zone.
