Abstract
Directivity is the response of an electro acoustic transducer as a function of direction of the transmitted or incident acoustic wave in specified plane and at specified frequency [1]. Directivity pattern is a graphical description usually in polar coordinates [1]. This paper describes the establishment of directivity measurement system for an underwater electro-acoustic transducer. Motion controller in combination with the servo system is used to control the positioning of the transducer mounting mechanism and PXIe 6124-8 channel data acquisition system of National Instruments is used for data acquisition and analysis. LabVIEW programming is used for interface, control and recording data.
