Sonar and Target Motion Training
Sonar and Target Motion Training Course Description
This three-day Sonar and Target Motion Training is designed for SONAR systems engineers, combat systems engineers, undersea warfare professionals, and managers who wish to enhance their understanding of this discipline or become familiar with the “big picture” if they work outside of the discipline. Each topic is illustrated by worked numerical examples, using simulated or experimental data for actual undersea acoustic situations and geometries.
• What are of the various types of SONAR systems in use on Naval platforms today?
• What are the major principles governing their design and operation?
• How is the data produced by these systems used operationally to conduct Target Motion Analysis and USW?
• What are the typical commercial and scientific uses of SONAR and how do these relate to military use?
• What are the other military uses of SONAR systems (i.e. those NOT used to support Target Motion Analysis)?
• What are the major cost drivers for undersea acoustic systems?
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.
Sound and the Ocean Environment. Conductivity, Temperature, Depth (CTD). Sound Velocity Profiles. Refraction, Transmission Loss, Attenuation.
SONAR Equations Review of Active and Passive SONAR Equations, Decibels, Source Level, Sound Pressure Level, Intensity Level, Spectrum Level.
Signal Detection. Signals and Noise, Array Gain, Beamforming, BroadBand, NarrowBand.
SONAR System Fundamentals. 4. SONAR System Fundamentals. Review of major system components in a SONAR system (transducers, signal conditioning, digitization, signal processing, displays and controls). Review of various SONAR systems (Hull, Towed, SideScan, MultiBeam, Communications, Navigation, etc.)
SONAR Employment, Data and Information. Hull arrays, Towed Arrays. Their utilization to support Target Motion Analysis.
Target Motion Analysis (TMA). What it is, why it is done, how is SONAR used to support it, what other sensors are required to conduct it.
Time-Bearing Analysis. How relative target motion affects bearing rate, ship maneuvers to compute passive range estimates (Ekelund Range). Use of Time-Bearing information to assess target motion.
Time Frequency Analysis. Doppler shift, Received Frequency, Base Frequency, Corrected Frequency. Use of Time-Frequency information to assess target motion.
