Maintenance procedures 12 Provide the accurate physical location of the sensor (or its antenna) with reference to the vessel’s coordinate system. The position of certain sensors must be defined as an offset to the Ship Origin in the coordinate system to maximize performance. These offset values are all required to allow the SX90 system to give you as accurate information as possible.

The required accuracy of the offset and rotation angles depends on the accuracy requirements for the echo data.
Page 227 Do this as accurately as possible. Note The Kongsberg Seapath ® - and other GPS systems - allow you to define the MRU location in the positioning system. If this is done, the MRU offset values in the SX90 system must be set to 0 (zero) to avoid "dual compensation".

Procedure Make sure that all power to the hull unit is disconnected. Make sure that you have sufficient height between the hull and the dry dock floor. Lowering the transducer Use a spanner to open the door on the Motor Control Unit.
Page 294 Simrad SX90 Reference Manual Note Do not use high-pressure water, sandblasting, metal tools or strong solvents to clean the transducer. Do not damage the outer protective skin of the transducer. Allow the transducer surface to dry. Do a thorough visual inspection of the transducer.
Page 295 Maintenance procedures Painting the transducer face Marine growth (biological fouling) on the transducer face reduces the performance. We recommend that you paint the transducer face immediately after installation, and then again as often as required to maintain the protection. It is particularly important to do this if you operate in waters with a lot of marine growth.
Page 296 The anti-fouling paint will reduce the acoustical performance of the transducer.

Simrad SX90 Reference Manual Pulse Type function function allows you to select the "shape" of the transmitted pulses ("pings"). Pulse Type Different shapes have different qualities. Which pulse type to use depends on the current environmental conditions, your range to the target(s) and the type and speed of the target(s) you are observing.
Page 487 Functions and dialog boxes • Frequency modulated transmissions may provide a more stable echo presentation. You may see an increase in target detection because noise and reverberation are reduced. • HFM (Hyperbolic Frequency Modulation) pulses are less sensitive to Doppler. These pulses may be a better choice for fast moving targets.

Page 489: Bandwidth Function
Functions and dialog boxes will reduce the voltage level on the output capacitors, and this reduces the source level on the following transmissions. Longer pulses will also increase the blind zone close to the transducer and increase the reverberation level. For these reasons, the use of long pulse durations may not be the best choice.
Page 490: Frequency Function
Simrad SX90 Reference Manual Example If the chosen operating frequency is 26 kHz, and you set the bandwidth to 2 kHz, the frequency range in each transmission starts on 24 kHz and ends on 28 kHz. The bandwidth function does not apply to CW (Continuous Wave) transmissions.
Page 491: Horizontal Tx Sector Function
Functions and dialog boxes Description The use of multiple operating frequencies is mainly intended for suppression of interference from other hydroacoustic equipment. If several sonars are used in the same geographical area they should therefore use different centre frequencies. Also, the sound absorption in salt water decreases with the frequency.

Page 496: Agc (Automatic Gain Control) Function
Simrad SX90 Reference Manual AGC (Automatic Gain Control) function (Automatic Gain Control) function runs an automatic analysis of the echo strength. Based on this analysis the SX90 system maintains a proper dynamic range based on all the current echo values. This is done by automatically reducing the gain if you have reverberation and noise, or increasing the gain if the acoustical conditions permit it.
Page 497 Functions and dialog boxes The most practical way to use the AGC (Automatic Gain Control) is to first switch it off. Adjust the echo presentation using the normal gain functionality until you have the best possible result, then activate the AGC. The AGC works best with even background (homogenous noise conditions) and pronounced targets.

Simrad SX90 Reference Manual Layers and deflections Daily operation of the SX90 system may be disturbed by environmental situations that you are unable to control. Typical conditions are temperature and salinity layers, as well as deflections caused by increasing or decreasing water temperature.
Page 645: Sonar Beam Deflections
Concept descriptions Sonar beam deflections On warm days – especially during summer – the sea surface will be heated by the sun. The water temperature will gradually decrease with increasing depth. On cold days, you may experience the opposite. The cold water will be close to the surface, and the water temperature increases with increasing depth.
Page 646: What Is Sampling
Simrad SX90 Reference Manual What is sampling? The information from the transducer on the SX90 system is a continuous flow of analogue data. In signal processing, sampling is the reduction of this continuous signal to a discrete signal. A common example is exactly what we do in the SX90 system. We convert a sound wave (which is an analogue continuous-time signal) to a sequence of samples (which is a discrete-time signal).

Concept descriptions Acoustic noise Topics Introduction to the acoustic noise challenge, page 645 Contributing factors, page 645 Self noise, page 647 Ambient noise, page 650 Electrical self noise, page 650 Reverberation, page 651 Some means to reduce acoustic noise, page 652 Introduction to the acoustic noise challenge Even with the advanced noise filtering offered by the sonar system, we must address the noise challenge.
Page 648 Simrad SX90 Reference Manual • The properties of the target(s) • The signal-to-noise ratio The majority of these factors can neither be controlled nor improved by means of installation methods or transducer locations. The quality and properties of the transmitting and receiving systems are key factors during our product development, while our end user documentation aims to help you to make the right filter settings during operation.
Page 649: Self Noise
Concept descriptions The transducer can pick up noise from: • Biological disturbances • Interference • Cavitation • Propeller noise • Flow noise • Acoustic noise from other hydroacoustic systems The transducer cable is long. Electric noise from generators, pumps, cooling systems and other electric or electromechanical devices is easily picked up.
Page 650 Simrad SX90 Reference Manual Electrical noise Modern vessels are normally equipped with a lot of electric instruments such as hydroacoustic systems, radars, navigation systems, and communication equipment. Any electric instruments may in some cases cause electrical interference and noise. International regulations and certifications are used to control and reduce this, but even these are limited if the electrical systems are poorly installed and/or maintained.
Page 651 Concept descriptions • The laminar flow is a nicely ordered, parallel movement of the water. • The turbulent flow is a disorderly flow pattern, full of eddies. Turbulent flow Laminar flow Air bubbles Air bubbles absorb and reflect the sound energy, and they may in worst cases block the sound transmission altogether.

Concept descriptions Related topics Improving the recognition of fish and schools using receiver filters, page 117 Concept descriptions, page 638 Acoustic noise, page 645 Reverberation When you transmit an acoustic pulse into the water to search for a target, echoes will also be returned from any other objects in the beam.

Simrad SX90 Reference Manual In this situation you will be able to identify the upper school of fish, but the lower school will be hidden in the shadow of the seabed rock formation. In this situation you will see several weak echoes from the waves and from the rock on the bottom, but you will still be able to identify the school of fish.
Page 655 Concept descriptions Reducing flow noise The shape of the hull plating around the installation trunk opening must be as streamlined as possible. It is particularly important that the hull plating in front of the installation trunk is as smooth as possible. Important Be especially aware of bilge keels and sacrificial anodes.
Page 656 Simrad SX90 Reference Manual Reducing electrical noise Make sure that all units are properly grounded. This is important to avoid electrical noise. Use shielded cables with correct grounding. Separate the cables used by the SX90 system from other cables with high voltages, large currents or transients.
