Page 469: Pulse Type Function
Functions and dialog boxes 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 470 Simrad CS90 Reference Manual • 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 471 Functions and dialog boxes LFM (Linear Frequency Modulation) In LFM transmissions the frequency changes during the duration of the pulse. The change is linear. Use the function to define the centre frequency used by the Frequency transmitted pulse. Use the function to define the frequency range during Bandwidth the transmission.
Page 472: Bandwidth Function
Simrad CS90 Reference Manual 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.
Page 473: Frequency Function
Functions and dialog boxes Example If the chosen operating frequency is 80 kHz, and you set the bandwidth to 3 kHz, the frequency range in the transmission starts on 77 kHz and ends on 83 kHz. The bandwidth function does not apply to CW (Continuous Wave) transmissions. You can adjust the bandwidth to very low values.
Page 474: Horizontal Tx Sector Function
Simrad CS90 Reference Manual 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 479: Agc (Automatic Gain Control) Function
Functions and dialog boxes AGC (Automatic Gain Control) function (Automatic Gain Control) function runs an automatic analysis of the echo strength. Based on this analysis the CS90 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 480 Simrad CS90 Reference Manual 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.

Concept descriptions Vessel coordinate system The vessel coordinate system is established to define the relative physical locations of system units and sensors. When you have several different sensors and transducers on your vessel, and you wish each of them to provide accurate data, you need to know their relative physical positions. The antenna of a position sensor is typically mounted high above the superstructure, while a motion sensor is located close to the vessel’s centre of gravity.
Page 626 Simrad CS90 Reference Manual antennas, echo sounder and sonar transducers, motion reference units, etc.) are referenced to the origin. In most cases, the location of the vessel’s "official" origin has been defined by the designer or shipyard.

Simrad CS90 Reference Manual Layers and deflections Daily operation of the CS90 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 629: 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 630: What Is Sampling
Simrad CS90 Reference Manual What is sampling? The information from the transducer on the CS90 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 CS90 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 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 634 Simrad CS90 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 640 Simrad CS90 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 CS90 system from other cables with high voltages, large currents or transients.
