摘要

Abstract

A simple algorithm using an impulse response for a rectangular piston element is discussed. The impulse response of linear phased array is obtained by summing the impulse responses of rectangular piston elements with different delay times. The output response of the linear wide-band array is equal to the convolution of impulse response functions with wide-band pulse exciting signal. Sound field distributions and impulse responses of three kinds of transducers are compared. The results can be used to optimize the parameters of the linear phased array transducers used in ultrasonic imaging in nondestructive testing (NDT).
