Sonar Transducer Design Training


Sonar Transducer Design Training Course Description

This three-day Sonar Transducer Design Training is designed for sonar system design engineers, managers, and system engineers who wish to enhance their understanding of sonar transducer design and how the sonar transducer fits into and dictates the greater sonar system design. Topics will be illustrated by worked numerical examples.

Customize It:

With onsite Training, courses can be scheduled on a date that is convenient for you, and because they can be scheduled at your location, you don’t incur travel costs and students won’t be away from home. Onsite classes can also be tailored to meet your needs. You might shorten a 5-day class into a 3-day class, or combine portions of several related courses into a single course, or have the instructor vary the emphasis of topics depending on your staff’s and site’s requirements.

Course Content:

Overview Review of how transducer and performance fits into overall sonar system design.

Waves in Fluid Media. To understand basic transducer design principals, the student needs to given a background on how the transducer creates sound energy and how this energy propagates in fluid media. This section reviews the basics of sound propagation in fluid media and includes a review of the following topics:
Plane Waves
Radiation from Spheres
Linear Apertures Beam Patterns
Planar Apertures Beam Patterns
Directivity and Directivity Index
Scattering and Diffraction
Radiation Impedance
Transmission Phenomena
Absorption and Attenuation of Sound

Equivalent Circuits: Transducers are generally modeled as equivalent electrical circuits. A basic understanding of this approach will enable the student to understand the relationship between transducer parameters and performance and conduct basic analysis of transducer designs. This section will build on the following topics:
Mechanical Equivalent Circuits
Acoustical Equivalent Circuits
Combining Mechanical and Acoustical Equivalent Circuits

Waves in Solid Media: A transducer is constructed of solid structural elements. As such, the student needs to be provided with a background in how sound waves propagate through solid media. This section builds on the previous section and develops equivalent circuit models for various transducer elements. Piezoelectricity is introduced in this section. This section reviews the following topics:
Waves in Homogeneous, Elastic Solid Media
The electro-mechanical coupling coefficient
Waves in Piezoelectric, Elastic Solid Media

Sonar Projectors: This section combines the concepts of the previous sections and developes the basic concepts of sonar projector design. Basic concepts for modeling and analyzing sonar projector performance will be presented. Examples of sonar projectors will be presented and will include spherical projectors, cylindrical projectors, half wave-length projectors, tonpilz projectors, and flexural projectors. Limitation on performance of sonar projectors will be discussed.

Sonar Hydrophones: In this section, the basic concepts of sonar hydrophone design will be reviewed. This section will include the analysis of hydrophone noise and extraneous circuit noise that may interfere with hydrophone performance. Topics include:
Elements of Sonar Hydrophone Design
Analysis of Noise in Hydrophone and Preamplifier Systems
Specific Application in Sonar Hydronpone Design
Hydrostatic hydrophones
Spherical hydrophones
Cylindrical hydrophones
The affect of a fill fluid on hydrophone performance
