Abstract
Some features in the formation of signals of an angle linear transducer with a phased array are considered. The directivity characteristic is calculated as a function of the number of radiating elements, the dimensions of an array, the reference entrance angle, etc. The manner in which the spreading of a wavefront and the changes in the transformation coefficient influence the directivity characteristic in the case of focusing a signal towards the current entrance angle is shown. The directivity characteristics of the signals of an angle phased-array transducer and an elongated element radiating into a prism are compared.
