Various techniques to generate pseudo-orthogonal excitations for Ultrasonic Non Destructive Testing (UT-NDT) are discussed, with the constraint that they deliver constant-envelope waveforms and they are FM based. Pseudo-orthogonal excitations enable multiple Tx probes to be operated simultaneously so that many measurements can be taken at once.

Abstract
Various techniques to generate pseudo-orthogonal excitations for Ultrasonic Non Destructive Testing (UT-NDT) are discussed, with the constraint that they deliver constant-envelope waveforms and they are FM based. Pseudo-orthogonal excitations enable multiple Tx probes to be operated simultaneously so that many measurements can be taken at once. The constraints assure minimal disruption of conventional hardware arrangements and guarantee a good exploitation of the power conversion abilities of the Tx probes. The goal is to seek a progressive management of the trade-ofl' between contrasting merit factors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
