An Ultrasonic Device for Signal Processing,

Abstract

The invention concerns the field of analog processing of the signals of phased antenna arrays in sonar and radar. The ultrasonic signal processor announced in USSR Patent 319986 does not eliminate spurious signals. In the present device, in order to remove spurious signals, the polygon is in the form of a piezoceramic plate, at one side of which the electrodes of a retransmitting array and the electrodes of a counting array are jointly deposited, while the edges of this side are covered with an absorber of ultrasonic surface waves.
