Simulation of the operation of a normal transducer with a phased array in the transmission mode
Source abstract
Abstract
The main principles of the formation of signals of a linear normal phased-array transducer are considered. Directivity characteristics (DCs) are calculated as functions of the number of emitting elements, the array dimensions, and the distance. It has been established that the DCs of such a transducer are similar to the pulsed DCs of an ordinary transducer of somewhat smaller dimensions. The presence of the near-field zone within which the DCs are formed is shown.
