Abstract:

Computer results indicate that array behavior is influenced by array size, piston size, and internal impedance of the transducer. The center element of an N-by-N array probably does not have a radiation impedance representative of the average of the array, unless the array is prohibitively large. Also, computer results show that the effects of guard rows of undriven elements surrounding an array decrease as the array becomes larger and as velocity control improves for the array. Author
