ABSTRACT:
A single test transducer or a line array of test transducers is placed above the transducers of an array under test and provided with a simulated flow noise signal. The response of all of the transducers under test is derived and stored whereupon the test transducer or line array of test transducers is moved to a subsequent position wherein the process is repeated. After all positions are indexed, the stored signals representing the outputs of all of the transducers of the array under test for all transmissions are combined and processed to derive a transducer array output signal for analysis purposes.
