CALCULATION OF A BOTTOM ECHO FOR MODEL OF THE STRAIGHT BEAM TRANSDUCER WITH THE RECTANGULAR PHASED ARRAY
(pp. 39-51)

Abstract. The computer simulation of a bottom echo of the straight beam transducer with the rectangular phased array for two versions of a fo-cusing is conducted. The confrontation of outcomes of calculations of relation of change of normalized amplitude of a bottom echo of the transducer to the phased array from distance with usage of analytical expressions and straight lines by numerical toting of echoes in view of a focusing has shown their coincidence. Is established, that as against customary transducers, the change of the wave size of transducers with the phased arrays notably has an effect for value of amplitude of a bottom echo in a maximum. The influencing on relation of a base signal of a focusing on fixed distance is reviewed.

Keywords: straight beam transducer, rectangular phased array, bottom echo, full focusing, central focusing, wave number, near field, point of reflection, fixed distance of a focusing.
