Abstract :
A multielement surface acoustic wave transducer array of very small aperture and separation has been fabricated on PZT substrates and the phase Scanning of the resultant acoustic beam from such a transducer array has been demonstrated. In addition to its use as an acoustic beam scanner, the transducer array may form a new type of signal processor, requiring no phase shifters or delay lines, for sonars and electromagnetic phased-array antenna applications.
