Page 21 17 System description The Simrad SU90 is a low-frequency fish-finding sonar with 360-degree coverage and long range. The SU90 system is designed for medium and large sized fishing vessels.It was originally developed for purse seiners, but experience has proven that it is also well suitable for trawlers.
Page 22 Simrad SU90 Reference Manual If high performance is your number 1 criteria when choosing a sonar; such as long range, high resolution, narrow beams and high source levels, this is your natural choice. We made no compromises during the design of the SU90 system. Our goal was simply to make the ultimate high performance fish finding sonar.
Page 23 The SU90 system is equipped with the celebrated signal processing software developed by Kongsberg Discovery. This includes Hyperbolic FM (HFM) transmissions. This pulse type is also known as "chirp". It ensures a clutter free picture with very high resolution in range.

Page 77 Operating procedures 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.
Page 78 Simrad SU90 Reference Manual Reducing propeller noise and interference with the Noise Filter Unless you synchronize the transmissions from your other hydroacoustic systems you may have an issue with interference. Even with synchronization activated the noise from other nearby vessels may cause noise.
Page 79 Operating procedures About this task Reverberation is often regarded as noise. There are several types of reverberation. Volume reverberation The volume reverberation is caused by minute plankton and air-bubbles in the water. This reverberation has often daily cycles in intensity. Surface reverberation The surface reverberation depends on the weather condition and the waves.

If you have noise problems, or you are bothered with for example smaller fish (different species), jellyfish or plankton, you can use the function to adjust the sensitivity. The target Minimum Threshold strength (TS) for a single target must exceed this threshold (in dB) to be accepted.
Page 642 Simrad SU90 Reference Manual Several single targets occurring at the same range will give you echoes in different parts of the beam’s cross section. To remove the bad targets, the angle (phase) between the samples in the echo are measured. If the angle is too large, the echoes are deleted.
Page 643 Functions and dialog boxes They also define the range of target samples which are used for Fourier transformation to create the target strength frequency response (the curve in the TS(f) information pane) and the target position phase values. Increasing the distance values will require the targets to be further separated, but can increase the frequency resolution for the target strength frequency response (in the TS(f) information pane).
Page 644 Simrad SU90 Reference Manual Note The measurement accuracy in the Size Distribution information pane depends on the vertical angle of the inspection beam. A beam that points nearly straight down corresponds to a traditional echo sounder. This gives the best accuracy since the fish is then viewed from above.

Page 647 Concept descriptions Important settings Topics AGC (Automatic Gain Control), page 645 TVG (Time Variable Gain), page 646 AGC (Automatic Gain Control) (Automatic Gain Control) function runs an automatic analysis of the echo strength. Based on this analysis the SU90 system maintains a proper dynamic range based on all the current echo values.
Page 648 Simrad SU90 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.
Page 649 Concept descriptions The automatic gain control (AGC) may override the effect of the TVG (Time Varied Gain). If you want to examine weak echoes that are very close to your vessel, use a low TVG setting (for example, 10 log R) or turn the TVG off. If a school is hard to see or follow when it moves closer to your vessel, try to reduce the TVG setting.

Page 652 Simrad SU90 Reference Manual 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.
Page 653 Concept descriptions Vessel coordinate system origin The origin is the common reference point where all three axis in the vessel coordinate system meet. All physical locations of the vessel’s sensors (radar and positioning system antennas, echo sounder and sonar transducers, motion reference units, etc.) are referenced to the origin.

Page 657 Concept descriptions What is sampling? The information from the transducer on the SU90 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 SU90 system. We convert a sound wave (which is an analogue continuous-time signal) to a sequence of samples (which is a discrete-time signal).

Page 661 Concept descriptions 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. Propeller noise Propeller noise is often the main source of noise at higher vessel speeds. Variable pitch propellers or fast moving propellers usually make more noise than fixed propellers or slow moving propellers.
Page 662 Simrad SU90 Reference Manual 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. The boundary layer increases in thickness when it becomes turbulent. The boundary layer is thin in the forward part of the vessel hull, and increases as it moves aft.
Page 663 Concept descriptions Concept descriptions on page 644 Acoustic noise on page 656 Ambient noise Ambient noise is usually not a limiting factor to the performance of sonars and echo sounders. The ambient noise may be split up as follows: • : Air bubbles, seismic disturbances, waves, boundary turbulence, etc.
Page 664 Simrad SU90 Reference Manual 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. The energy reflected from these "unwanted" objects is referred to as reverberation.
Page 665 Concept descriptions 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. The reverberation is caused by the transmission pulse itself. It can only be reduced by shortening the pulse duration or using a smaller beamwidth.
Page 666 Simrad SU90 Reference Manual Reducing machinery noise The hull unit must be installed far away from the engine room. The main engine and relevant auxiliary engines and equipment must be fixed to rigid foundations to avoid vibrations.
