چکیده مقاله:
An improved method for ultrasonic location of multiple flaws using perpendicular ultrasonic arrays,working in near-field conditions, is presented 1be method uses the pulse-echo technique and is basedon the processing of the information acquired by both the elemental emitting transducers and theiradjacent ones. This type of processing improves the performance of a previous method that sometimes presents limitations for the detection of multiples flaws. This new method is applied to aset of ultrasonic traces:, obtained with an ultrasonic prototype specifically designed for testing this method, showing the improvement obtained in imaging results
