A Transducer for Bottom-Scattering Measurements

Abstract

An omnidirectional 25-kHz transducer has been designed for use in bottom-scattering measurements. The transducer can be used either as a projector or, when fitted with a preamplifier, as a hydrophone. The requirements for the design are presented and solved with mathematical modeling and analysis. A comparison between theory and measured performance is given. The design of a low-noise preamplifier with integrated circuits is described. Keywords: Sonar transducers; Omnidirectional transducers; Acoustic scattering; Ocean bottom; Acoustic impedance; Mathematical models; Acoustic analysis; Acoustic measurement.
