2. SYSTEM DESCRIPTION
2.1 INTRODUCTION
This section explains the theory of operation of the SL 30/35 Mechanical Scanning
Sonar System.
2.1.1 Basic Principles
• Sound waves travel very efficiently through water.
• A sound pulse can be projected thr ough water in a controlled direction with the
sonar transducer.
• An object in the path of the projected sound pulse will reflect some sound pulse
back toward the sonar transducer.
• The speed of the sound pulse projected through the water can be predicted for
given conditions.
2.1.2 Determining Target Position
The SL 30/35 scanning sonar processor measures the time from the start of the
sound pulse projected through water, to the r eception of the sound pulse ref lected
back to the sonar transducer. The measured time is then convert ed to distance by
using the speed of sound through water.
Since the sound pulse is projected in a known direction, the bearing of the reflected
object is also known. This makes it possible t o locate the object with respect t o the
sonar transducer; the information will be used to plot the position of the reflected
target on a video graphic display monitor.
2.1.3 Forming an Image
The sound pulse projected will be attenuated as it travels through the water from t he
transducer to the target and back. Much of this att enuation is a predictable function
of the total time or the dist ance the sound pulse traveled through water. Increasing
the receiving gain with time can compensate for this decrease in the signal level.
This is done automatically in the sonar with a Time Varying Gain circuit.

Port Coquitlam, BC - Canada
974-25007001/2.0 SL 30/35 Hull Sonar Operators Manual
Page 2.4 System Description
After the TVG correction, the absolute levels of the received signals will be
determined by the acoustic response of the ref lect ing target.
The sonar processor system repeatedly measures the TVG corrected target levels
by digitizing a sequence of samples after each sound pulse transmission. Each
sample is then plotted on the video display at the appropriate position according to
its range and bearing. The level of the target strength sample determines the color
used to plot each sample.
The process can be repeated with the transducer pointed in different directions,
forming an image of a large area of the bot t om and displaying it on the video screen.
2.1.4 Wheelhouse Units Description
The following paragraphs will describe the key features of the W heelhouse Units of
the SL 30/35 Hull Sonar.
2.1.4.1 Display Monitor
The display monitor required for the SL 30/35 can be either a VGA “CRT” type or
any commercial LCD monitor. In order t o have the full benefit of high resolution, we
recommend that you select the Simrad rug gedized LCD colour monitor. T he Simrad
colour monitors are available in two sizes, 18” and 20”. The monitor can be desk,
ceiling, or flush mounted into the bridge console.
The Simrad LCD monitor will run on 110/240VAC, 50/60Hz or on 24VDC, +/- 10%.
All mounting hardware is included.
2.1.4.2 Processor Unit

3. SL 30/35 CONTROL PANEL OPERATION
3.1 INTRODUCTION
The SL 30/35 Sonar uses a Control Panel for the most frequently needed
adjustments and a software menu system f or less frequently needed controls. This
chapter describes how to use the Control Panel to operate the sonar .
3.2 CONTROL PANEL
A thorough understanding of the system functions and controls is necessary to
optimize the overall performance. Sonar condit ions vary, sometimes drastically, and
it is not possible to identify proper sett ings that will provide the best sonar image at
all times.
Careful study of the information in this manual is highly recommended, preferably
while exploring the sonar’s various functions. System operation is a dynamic activity
requiring regular adjustment and fine-tuning to achieve the best possible results
under varying environmental conditions.
The Control Panel Buttons are described in the following paragraphs.

4.13 HOW TO CONNECT AND SETUP A HEAD (FIRST TIME OPERATION)
The first time you run the SL35 Sonar program, you must configure the system for
your hardware as follows:
• Be sure the dongle is connected to a printer port on your com put er
• Be sure the sonar head has been connected to a serial port and has power
• Start the SL35 program by double clicking on its icon
• In the Configuration menu, select Connect Heads. The System Conf iguration
dialog box should appear showing every COM port that is available on your
computer
• Click on the COM port you want to use for connection to t he sonar head. For the
example, we will select COM2
• The box COM2 Configuration should appear showing the Port Hardware
Address for COM2.(Click here to see example)
• Check the Enable for Head Control box, then reboot the computer
• In a few seconds, the head should be detected, and the System Configuration:
Devices page should change to show the Head Name, Part Number and Serial
Number
• You can change the name of the sonar head at this point. Just select t he head in
the tree structure and then click in the Head Name edit box and type the name
you want to give that head. Note that this name will be used from t his point on to
reference the selected head throug h out the operational life time of the system
The name is persistent and will be used the next time you run the sonar system.
It will however, be replaced by a generic name the next time you go through
automatic detection of the heads on t he t elem e t r y line
• Click the OK button
4.14 HOW TO USE THE SONAR (SOME RULES OF THUMB)
Following are some general guidelines on how to use and adjust the sonar for many
applications:
Most of the palettes have a unique 'saturation' color to indicat e maximum echo
strengths. Any echo with a strength beyond this is shown in the same color. If
large parts of the image are being shown in this saturation color, you have

probably set the gain too high. Adjust the gain so that about only about 5% of
the total image is shown in the saturation color
If you are trying to track a moving tar get , or track a targ et f r om a moving vehicle,
use the scan reverse button (or Scan Reverse in the Operations Menu) to
improve the update rate on the targ et
Limit the Sector Width to the area of interest to m aximize the update rate. (See
Control Panel)
Use a higher Scan Speed when highest update rate is important. (See Contro l
Panel)
Use the slowest Scan Speed when you are trying to discern a small target or
require maximum detail in the im age
Set the Range to the shortest setting that allows you to see what you need to
see. This will give you the highest update rate and the best image quality. (See
Control Panel)
Always keep in mind the overall geometry of the situation, including the f act that
the sonar beam is fan shaped and becomes very narrow the closer you are t o
the transducer. As you move closer and closer to a t arg et, it is q uite possible f or
it to disappear simply because it has moved over or under the beam
4.15 HOW TO RESET TO THE FACTORY DEFAULT SETTINGS
To reset all sonar settings to their factory default values:
• Select Factory Reset in the Operations menu
• Select Yes when you are asked if you want to proceed
4.16 HOW TO USE THE BASIC SONAR CONTROLS

• Adjust the Range control to the setting you need
• Adjust the Sector Heading and Width controls so the sonar will scan the area
you want to cover
• Adjust the Scan Speed as desired. This will trade off image quality against
update rate
• Adjust the Gain control; a good starting point is 50 percent
4.17 HOW TO SELECT UNITS OF MEASURE (FEET, YARDS, METERS)
To select the units of measure for the sonar:
• In the Configuration Menu, select Parameters to open the Parameters | Units of
Measure dialog box
• Click a radio button in the Distance group to select the distance units you want
to use
• Click a radio button in the Temperature group to select the temperature units
you want to use
• Click the OK button
4.18 HOW TO SET OR ESTIMATE THE VELOCITY OF SOUND

local conditions.
If you have a known or measured value for the local sound velocity, enter it as
follows:
• In the Configuration Menu, select Parameters
• Click on the Sound Velocity tab to open the Parameters | Sound Velocit y dialog
box
• Enter the known value in the Value to be Used box. Caution: Be sure the units
of measure are the same for t he known value and the sonar, i.e. both in meters
per second or both in feet per second

the Value to be Used box
• Click the OK button
4.19 HOW TO INTERPRET THE SONAR IMAGE
4.19.1 The Color Palette
The sonar image is a map of t he echo returns over the scanned area. A sequence
of colors is used to show the relative strengths of the returns. Several colour
schemes or image palettes are available. Most of them use dar ke r colors t o indicate
weak returns and brighter, lighter colors to indicate the stronger returns.
4.19.2 Bright Spots
Bright spots in the image indicate strong sonar tar gets. Generally, this indicates a
hard, highly reflective surface.
4.19.3 Dark Spots
Dark spots in the image indicate either areas of low reflectivity (soft areas) or
possibly an acoustic shadow zone behind a target.

Port Coquitlam, BC - Canada
974-25007001/2.0 SL 30/35 Hull Sonar Operators Manual
Page 4.16 Menu and Software Description
4.19.4 Shadows
Most targets will block the transmission of sound either by reflecting it or absorbing
it. This will leave a shadowed area beyond the target that is not ensonified and
therefore will not generate any echoes. T his is very similar to the shadow f ormed
when an object is illuminated with a single light source. The shadow behind a target
can often yield more information about the targ et than t he ref lections f rom the target
itself. The shadow will often reveal the shape of the target , but you must r emember
that the shape will usually be distorted according to the position of the sonar head
relative to the target and the bott om, and according to t he slope of the bott om. It is
often possible to estimate the heig ht of a bottom target based on the length of the
shadow and the known height of the sonar ahead.
4.19.5 Noise and Interference
It is usually easy to recognize interference from other acoustic sources such as echo
sounders, pingers or other sonars. These sources all produce pulses at regularly
timed intervals and will therefore tend to creat e a regular or symmetrical pat tern of
'blips' on the screen. Electrical interference usually occurs at a m uch higher periodic
rate, and will tend to appear as spiral patterns on the screen. Mechanical noise
sources such as propellers, hydraulic pumps, and thrusters, are usually more
directional and tend to show up only when the sonar head is pointing directly
towards them.
4.19.6 Masking Effects
Sonar signals are easily blocked by air or gas bubbles in the water or on the
transducer face. As an example, the aeration present in t he wake of a vessel will
often last for ten to twenty minutes and effectively mask out any sonar returns on the
far side. The aeration block s the outgoing pulses as well as any returns. Another
source of gas or air bubbles can be found when a sea bottom containing
decomposing organic matter is disturbed by dredging or plowing.

Menu and Software Description Page 4.1
4.19.7 Range Scale and Target Size
When looking at any sonar image you must keep in mind the r ange scale you are
using, the position of the sonar relative to t he tar get you are looking f or , and t he size
of the target. For example, a tar get the size of a beer can will be very small and
probably not visible on a one hundred meter range scale.
4.19.8 Mirroring Effects
If you try using the sonar inside a rectang ular tank such as a swimming pool, it is
quite likely that you will see phantom targets out side the t ank boundary. T his occurs
because the tank walls are hard and smooth and can reflect the sound pulse f rom
one wall to another and finally back to the sonar transducer. The sound path is
similar to the path of a billiard ball making multiple bounces off t he sides and ends of
the table. Although it is not very common, there are occasions when this same
effect will happen in the sea, particularly when near certain large man made
structures. If you see something in the image that doesn't make sense, look at the
geometry or arrangement of the targets and see if a multiple path reflection could
explain the mis-plotted targets.
4.20 HOW TO GET THE HIGHEST RESOLUTION IMAGE
To get the highest possible image quality:
• Arrange for the sonar head t o be absolut ely stable in a fixed location
• Select the slowest possible scan speed
• If possible, adjust the computer display resolution to 1280 x 1024 and select the

Sonar networking is only possible if the computers are physically connected together
and can be seen through the Network Neighborhood. Users can use Local Area
Networks (LAN) or Peer To Peer networking for this purpose. Dial in networking is
limited to one of the machines being an NT-Server.
In the context of sonar operation, The SL30/35 can be in stand alone, server,
passive and active client mode.
4.28 STAND ALONE MODE
The default operating mode of the SL30/35. In this mode, it can operate sonar
heads or playback recorded data.
4.28.1 Server Mode
For systems that are equipped with sonar heads. SL30/35 switches to server m ode
when connecting to a remote client. It passes all its operational settings as well as
sonar data to the client. There can be only one server machine in a net work .
4.28.2 Passive Client Mode
For viewing sonar data generated by a remote machine in server mode. Passive
clients can not be operating sonar heads locally. The passive mode prevents the
user from controlling the remote sonar heads. Display settings such as palette,
window size, position etc. can be changed locally. There can be multiple client
machines attached to a single server.
4.28.3 Active Client Mode
For both viewing sonar data and actively control the sonar heads connected to the
remote server. Active clients can not be operating sonar heads locally. System

4.59.2.1 Sector View
The sector view allows you to select Up, Down, Left, and Rig ht as the orientation of
the sonar image display. Generally, you should choose the view that seems to
match the orientation of t he sonar head. If you are looking ahead, choose Sector
Up. If you are looking down as when profiling, you will probably want to choose
Sector Down.
4.59.2.2 Display Gain
The display Gain should normally be set to 100 percent. It should only be used in
playback to adjust the recorded signal levels if required. If you set this control to
less than 100 percent while using a sonar head as the data source, the system may
not operate at maximum speed. It is recommended to use the head gain (on the
Control panel as well as the Image Control Bar) during active sonar head operation.
4.59.2.3 Rx Gain Type
The Rx gain type is used to enable elementar y image processing for reverberation
control (RCG), automatic gain control (AGC) or a combination of the two. The Rx
Gain Response is the severity of the gain control. Note that these operations are
computationally expensive and may compromise system performance. The
algorithm for the AGC adjusts the gain applied t o each sample of a ping to m aintain
some nominal signal level. The leading edge of targets are therefore most visible
with the trailing edges fading away. The Reverberation control uses the average
signal level through a number of ping and uses that as a ref er ence to adj ust t he gain
to maintain some overall background sig nal. This has t he eff ect of increased gain in
low noise environment and small gain for highly noisy environment.
4.59.2.4 Scan marker
The scan market is used to enable or disable the marker on the sonar image
showing the current angle of the t r ansducer.
4.59.2.5 Grid control
The grid control selects the type of grid (Polar or Rectangular) as well as enabling
and disabling it.

sensors are attached to may be selected by the user.
• Check the Select check box.
4.59.5.3 Automatic File
The extension starts with an ".smb" and increments by one to ".001", ". 002", etc. as
the new volumes Naming option provides the user with automatic name generation
for the recorded file. The file name is g enerated based on the date and time of the
record session as shown "Month Day,Year,Hour-Minute-Seconds" Month is the
abbreviated followed by the two digit day with no space in between. The year is then
separated by commas on both sides followed by the two digit representation of t he
hour, minute and secondsare generated while the recording is in progress
During playback, user can not choose the specific sonar head or s ensor port to export from .
All that is available is the type of sensor data that the user wants to export.

the vessel.
Horizontal/Vert Fan Provides a 180 degree Horizontal Sector main display with a Vertical
Fan display in a second window. This allows the operator to observe
the history of fish movement and distribution in real time. The
Vertical Fan provides the range, depth, and heading of the fish
echoes.
Horiz with History Provides a 180 degree Horizontal Sector main display with the history
displayed in a second window. This allows the operator th observe
the history of fish movement and distribution equivalent to about four
full 360 degree scans. It is also us eful for detecting bottom f ish and
reefs.
The Scan Speed box allows you to choose the scanning speed f or the head. The slower
scan speeds will generate the nicest looking images.
The Pause Head button will make the head stop scanning and pinging.
The Sector controls allow you to adjust the Heading of the area to be scanned as well as the
Width of the sector. Use the slider controls or the increase-decrease buttons for either
adjustment. The area to be scanned is shown graphically above these controls.
Tilt controls allow you to control the tilt angle of the transducer up or down. T he Auto Tilt
Step option enables the automatic stepping of the tilt axis at the end of eac h azimuth sector
sweep. As an example, if this option is enabled, after the azimuth axis has stepped through its
complete sector width, the tilt axis is stepped by as much as its Step size, and the azimuth
starts to sweep back its s ector width in the r everse direction. Max and Min slider bars control
the sector limits of the tilt axis. These limits are equivalent to sector width and heading and
determine the sweep sector of the tilt.
Stabilization control enables the automatic tilt angle adjustment with the overall Pitch and
Roll angle of the head. If the head is equipped with pitch and roll sensors , then prior to each
acoustic ping the head reads its pitch and roll angle, calculates the offsets required to
maintain the transducer at its desired angle and changes the tilt angle to compensate.

The Uplink Baud Rate control is used to set the rate at which data is sent f rom the head to
the surface. You will normally want to set this control to as high a rate as your system will
support without generating too many errors.
When Compression is set to On, the c olor depth of the sonar image will be an eighth of its
maximum through a reduction in the signal amplitude res olution. This however, increases the
uplink speed of the sonar data, thereby increasing system performance. The option can
usually be set to On due to negligible effect of the loss in color depth.
The Pulse Length control can be used to set the desired transm it pulse length on heads that
support this feature. Generally, a shorter pulse length will give a sharper image but with
reduced range. By default, the system adjusts the pulse length at dif ferent range and display
mode settings according to the selection of the Optimize resolution or Maximize Range.
The automatic selec tion of the pulse length can be disabled by clicking the Manual Setup
box.
Bandwidth is used to adjust the analog bandwidth of the received s ignal. This option is only
available for analog telemetry sonar heads. An Analog Interface Module (AIM) is requir ed to
be able to run an analog telemetry sonar head with this system. The contr ol selections are
