Page 11: System Description
System description SYSTEM DESCRIPTION Introduction The Simrad SH80 sonar is an omnidirectional high frequency sonar, designed for all sized fishing vessels, both purse seiners and trawlers. The standard frequency is 116 kHz (multiple frequencies as option), and the beam can be electronically tilted from +10 to –60 degrees.
Page 12: System Overview
The Sonar Processor Unit contains a ruggedized computer, which runs the Microsoft Windows XP® operating system. The software has been modified by Simrad to suit the SH80 sonar requirements. The unit holds a CD R/WR unit to be used for future software upgrades.
Page 13: Sonar Room Units
System description Sonar room units The Transceiver Unit is located in the sonar room, close to the Hull Unit. One signal cable is used for communication with the Sonar Interface Unit in the wheelhouse. The transceiver performs the signal processing and the digital beamforming of the 240 transmitters and 480 receiver channels, which are located on the eight identical transceiver boards.

Page 16: Options
The options described below are pre-programmed into the standard software version, and a code word is required to make the actual option available. Simrad offers a 1 month free test period for certain options. Note that the Scientific Output function is not available for such a test period.
Page 17: Functional Description
System description Functional description Introduction The basic principles of the SH80 sonar are unique because of the 240 transmitter and 480 receiver channels with their transducer elements spread around on the cylindrical transducer array. The transmission, reception and data processing are under computer control, and the powerful capabilities of the sonar are the results of sophisticated digital signal processing software and state of the art hardware.
Page 18 Simrad SH80 60 degrees vertical slice Omni/Vertical combination In addition to the Omni picture, the vertical slice is especially useful for visualizing the vertical distribution of a school of fish. In that way, it is not necessary to go over the target to see the distribution on the echo sounder, which often results in a spreading of the school.
Page 19: Stabilization System
System description Stabilization system When the beam stabilizer is activated, both horizontal and vertical beams will be stabilized electronically for roll and pitch movements up to ±20 degrees. The beam direction will then change continuously according to the vessel’s movements, and secure an optimal contact with the targets even in rough seas.
Page 20: Transmission
Simrad SH80 However, the sound absorption in salt water increases with the frequency, thus giving the lower frequencies a longer detection range. RCG (Reverberation Controlled Gain) The RCG filter senses the noise level (reverberation, propeller noise, etc.), and adjusts the gain individually for each of the 64 receiver beams in order to eliminate noise on the display.
Page 21 System description When the stabilisation system is active, the tilt angle for each beam will automatically be corrected relative to the vessel’s pitch and roll movements. Related topics → Frequency options, page 6 850-164385 / Rev.C...
Page 22: Peripheral Equipment
• A (D)GPS may be connected to the SH80 sonar to establish the vessels position and provide cursor and marker latitude and longitude. • Simrad echo sounders (EQ, ES and EK Series) provides a bottom plot on the catch data page. • Simrad PI32 and PI44 Catch Monitoring systems provide the net depth in digits and bars on the catch data presentation.
Page 23: Display Modes
Display modes DISPLAY MODES Introduction This chapter describes the SH80 display modes. The various modes represent the graphical presentation of sonar data. Several display modes are available to present the best possible presentations as well as flexible choices for a large range of user applications.
Page 24 Simrad SH80 Bow Up When Bow Up mode is selected, the vessel symbol is stationary on the screen with the bow pointing upwards. The echo presentation covers 360 degrees around the vessel, and all echoes are updated for every ping. The distance from the vessel symbol to the outer echo ring is equal to the selected range.
Page 25: North Up
Display modes North Up When the North Up mode is selected, true north is always up on the screen. The vessel symbol is stationary with the bow pointing in the vessle’s course direction. The movement of the echoes across the screen are controlled by a combination of the vessel’s course and speed and the target’s own movements.
Page 26: True Motion
Simrad SH80 True Motion When the True Motion mode is selected, the picture is locked to a geographical position, where the vessel moves around the screen according to its present course and speed. All echoes are always presented in their correct position relative to the vessel, and their movements on the screen will be a true representation of the movements of the targets through the water.
Page 27: Audio
Display modes 180°/Audio When the 180°/Audio mode is selected, the upper half of the screen shows a 180 degrees bow-up presentation, while the lower part is used for a recording of the audio channel. The audio channel is shown with a continuous white line in the horizontal picture, and it can be trained in any direction.
Page 28: Vertical
Simrad SH80 270°/Vertical The 270°/Vertical mode is specially designed for purse seining. The vertical half slice is displayed in the lower left corner for normal setting with the net on the starboard side. If the net is set on the port side, the 60 degrees vertical slice will be displayed in the lower right hand corner.
Page 29: Bow Up / Vertical
Display modes Bow Up / Vertical When the Bow Up / Vertical mode is selected, the picture is divided into three sections; where the left side is a bow-up presentation similar to the bow-up presentation previously described. The upper part on the right hand side is a catch data presentation, while the lower part is a 60 degree vertical slice presentation.
Page 30 Simrad SH80 True Motion/Vertical When the True Motion/Vertical mode is selected, the picture is divided into three sections; where the left side is a True motion presentation similar to the true motion presentation previously described. The upper part on the right-hand side is a Catch data presentation, while the lower part is a 60 degrees Vertical slice presentation.
Page 31 Display modes Dual 1 The Dual 1 mode is a kind of “two sonars in one” operation, where each presentation is updated for every second transmission. All settings can be set individually for each of the two presentations. This makes the dual mode especially useful for optimizing settings by directly comparing the two presentations.
Page 32 Simrad SH80 Dual 2 The Dual 2 mode is very similar to the Dual 1 mode previously described, but the “two sonars” are presented next to each other. All settings can still be set individually for each of the two presentations.

Page 41 Sonar Operating Panel Trackball The trackball controls the cursor. The cursor changes appearance in relation to its location on the screen: • An Orange cursor in the echo field. • An arrow in the menu field. • A negative or positive sign at each end of the menu buttons. The negative or positive sign indicates the direction in which the corresponding parameter values will be changed when the Select button is pressed.
Page 42: Train
Simrad SH80 Train The audio channel is displayed as a continuous white line. It can be trained either manually or automatically. The bearing angle is displayed in the upper right-hand corner of the display, indicated relative to the bow. Manual In the Manual mode the train left (arrow) or train right (arrow) buttons are used to direct the audio line to the desired bearing.
Page 43 Sonar Operating Panel When the Auto Tilt function is activated in the Position Track mode the tilt search centre is automatically adjusted with regard to the distance to the tracked position. Target track To track a target, place the cursor over the desired location and press the Target Track button.
Page 44: Tilt
Simrad SH80 Tilt Manual tilt In Manual mode the transducer may be tilted within the systems limits by pressing the Tilt up (arrow) or Tilt down (arrow) buttons. Pressing either button once changes the tilt angle in steps of 1 degree. Pressing and holding either button continuously changes the tilt angle until pressure is removed.
