Abstract

Sidescan sonar uses the fan type beam which has horizontally narrow and vertically somewhat wide beam pattern. To construct such a beam we will use an array of transducers. In case of using single transducer it must have a high frequency to have the fan type beam, but in case of using an array it must have to be high frequency. We are planning to use 30 kHz transducers for our sidescan sonar under development. This paper shows ways of designing a narrow beam for the sidescan sonar system by illustrating various shapes of the beam patterns.
