Safety precautions
The Argus radar is connected to 115 VAC or 220 VAC - 50 or 60 Hz power; therefore, before
starting any work on the equipment, make sure that the power supply is switched off.
The system is equipped with fuses protecting the electronics devices from short circuits,
which may damage the equipment or cause fire.
Depending upon the material to be highlighted, the following attention headings are used in
this manual:
Danger: Before turning on the radar, make sure that no one is standing near the an-
tenna.
Warning: The electronics of the equipment are supplied with mains power, also when

Preface | Argus Radar Operator Manual
High voltage
Radar equipment includes high voltage that can cause injury or loss of life. Danger exists only
when the units are opened and exposing internal circuits, as when servicing the equipment.
The ARGUS Radar has been carefully designed to protect personnel from possible injury from
high voltages.
Nevertheless, it is recommended that the Main Power Line shall always be OFF, as an added
protection when inspecting or servicing the equipment.
Although every effort has been made to eliminate danger to personnel, no responsibility is
accepted for any injury or loss of life suffered in connection with this equipment.
Safety switch
The Radar Unit is provided with a safety switch, which disables the antenna rotation during
maintenance and avoids high voltage damage. Always turn the safety switch off, whenever
the procedure advises to do so (for instance, before performing any maintenance or installa-
tion procedure). Ignoring safety switch operation may produce hazard of electrocution as well
as other severe injures.
Safety precautions
Purpose
The described safety precautions are applicable to the ARGUS Radar System. Depending
upon the material to be highlighted, the following notes are used in this manual.
¼Note: An essential operating or maintenance procedure, condition or statement which must
be highlighted.
Whenever a precaution, relating specifically to a part of this manual is needed, the informa-
tion is given in the relevant part of the manual. Warnings and Cautions precede applicable
text.
Safety operations
Main power line is always present on terminal board and fuses. During normal operation
(front cover closed), the unit can quickly be disconnected from the main power line, setting
the relevant circuit breaker, located on the electric switchboard, to OFF.
Safety summary
The following are general safety precautions not related to any specific procedure and
therefore do not appear elsewhere in this manual. These are recommended precautions that
personnel must understand and apply during most phases of operation and maintenance.
KEEP AWAY FROM LIVE CIRCUIT
Operating personnel must at all times observe all safety regulations.
Do not replace components or make adjustments inside the unit with the high voltage sup-
ply turned ON. Under certain conditions, dangerous potentials may exist when the power
breaker is in OFF position, also due to charges retained by capacitors. To avoid casualties,
always remove power and discharge a circuit to ground before touching it.
DO NOT SERVICE OR ADJUST ALONE
Under no circumstances should any person initiate servicing or adjusting the unit without the
presence of someone capable of helping.
RESUSCITATION
Personnel working with or near high voltage should be familiar with modern methods of
resuscitation. Such information may be obtained from the Bureau of Medicine and Surgery.

4 | Preface | Argus Radar Operator Manual
Warning information
The following warnings will appear in the text of the technical manuals, and are repeated here
for emphasis.
Warning: Use extreme care when working on the unit once the cover has been
opened. The magnetron assembly operates at voltages that may prove fatal.
Warning: Beware of high voltage capacitors. It is necessary to short-circuit their
leads before performing any maintenance action on them.
Warning: On the electric switchboard, set the power breaker dedicated to the
present equipment to OFF and hang up a placard reading:“work in progress - do
not switch on”.
Warning: Set main line breaker to OFF before replacing a fuse. The voltage in
fuses are under the level which may prove fatal.
X-Ray radiation
X-ray radiation may be generated by Transceiver units and care must be taken to avoid pos-
sible harmful effects when they are opened for maintenance. When power is on, care should
be taken not to approach closer than 1 foot (12 cm) from the unit unless front cover is in
place.
Radio frequency radiation
Harmful effects (particularly to the eyes) may be caused by exposure of any part of the human
body to radio frequency mean power densities in excess of 100 mW/cm2. This power density
is exceeded at a distance of 1 foot (12 cm) or less, from the 12 ft. X-Band aerial (when station-
ary).
The system is however designed to disable radiation when the antenna is not rotating.
The pedestals have also been predisposed for the installation of an external safety switch,
which can be mounted on, or near the platform. This switch removes power from the
Pedestal eliminating the possibility of accidental operation during servicing and also causes
disabling of transmission.
Whenever it is necessary to disconnect the waveguide system from a radar transmitter for
maintenance purpose, the transmitter output should, when practicable, be terminated in
a matched load. If this is not possible, care should be taken to avoid standing in front of an
open-ended waveguide from which power is being radiated.
¼Note: NEVER look down on a waveguide from which power is being radiated.

General information
Introduction
The ARGUS Radar is a radar indicator with a presentation based on a raster scan principle.
The advantages of using the raster scan principles to produce a radar display are as follows:
• true daylight presentation
• continuous display of radar video
• high number of graphics that can be superimposed to the radar picture
• areas where all necessary navigational data can be presented at the same time.
The radar scans the horizon over a total of 360°, azimuth samples are converted and stored in
a memory, and then presented on a raster scan display. These conversion and memory logics
make the core (heart) of the indicator.
In order to have a display resolution similar or better as compared to a traditional radar
picture, very large memories are used. In addition, the display monitor is able to present
video data without loosing even the smallest information written into the memory. However,
various monitors with different resolutions can be connected to the ARGUS Radar System, so
depending on the choice of monitor, the graphic interface can be quite different from one
monitor to the next. The graphic layouts and widgets in this manual are examples only and
may therefore not appear exactly the same on the screen in your system.
In order to reduce the number of circuit boards (PCBs), a CPU performs multiple functions.
Therefore, the CPU has the total control of the system and gives the advantage to have very
sophisticated diagnostics and great flexibility.
Very large scale integrated micrologics are used.
A single card forms a complete sub-function and has very few connections to the rest of the
system.
The modular design in the base of the system and sub-units are easily replaced in case of
malfunction.
The ARGUS Radar performs the following operations:
• it receives the ship sensor’s data, which are:
GYRO - indicates the ship heading
LOG - indicates the ship speed
EPFS - indicates the ship position, speed and course
AIS - identifies the ships in the area
• it interfaces and receives signals from up to four transceivers (scanners), with relevant antenna,
and allows the operator to select the transceiver to be used for the presentation
• it processes the received signal in order to detect targets
• it processes the signal relevant to a target in order to obtain the target data: position, speed,
course, heading
• it automatically tracks a target in order to update the target data
• it shows the target position on the monitor.

Physical description
The ARGUS Radar System consists of the following units:
• Monitor Unit on which the data, command buttons inside the SYSTEM DATA AREA, and the
echoes with relevant targets inside the PPI AREA are displayed.
• Core Unit in which the ARGUS electronic boards are mounted.
• Keyboard Unit on which the hardware of the Control Panel is mounted.
• Scanner Unit – not included. Refer to Simrad ARGUS Radar Scanner – Technical Manual.
Monitor unit
The Argus Monitor Unit represents the visual interface between the Operator and the Equip-
ment. The equipment can be supplied with different types of Monitor Unit. Technical charac-
teristics are located in the next paragraph.
Control panel (keyboard)
The Control Panel is the interface on which the operator can insert data, change the working
parameters and perform the operations necessary for the correct use of the equipment.
The Control Panel features light indicators, pushbuttons, rotating knobs and a trackball, which
controls the equipment. For more details, refer to Chapter 2.
The Control Panel is connected to the Core Unit by means of a cable with connector.
Core unit
The Core Unit consists of the following main parts protected in a dedicated cabinet::
• the Antares Assy
• the Alpha Board
• the optional Alpha Expansion Board
• the Power Supply mounted on the Alpha Board
• the Line Filter
• the Main Power Switch
For details, refer to Simrad ARGUS Radar Installation & Service manual.
The boards are made up of multi-layers printed circuits using VLSI components; program-
mable gate arrays and microprocessors are used to achieve a high package density, functional
reliability and low power consumption.
Auxiliary indicators (Light Emitting Diodes) are also located on the boards to allow easy
scheduled test, troubleshooting and maintenance actions.
The Line Filter is fixed to the left lateral panel of the Core Unit by means of nuts. The supply
voltage (115 VAC – 220 VAC 50/60 Hz) is applied through the Main Power Switch to the Alpha
Board.
The Alpha Board is fixed on the left side of the Core Unit by means of screws. The board is
the interface between the Argus monitor, auxiliary navigation equipment (GYRO, GPS, LOG,
AIS…) and the TXRXs (transceivers) connected. The interconnection allows commands to be
transmitted or received through BNC connectors and the Terminal connectors.
General functioning description
The Argus monitor receives the following signals from the connected transceiver(s):
• Video Signal
• Trigger
• Azimuth (AZ)
• Heading Line (HL)
• TXRX Data
The data is applied to the TXRX interface block of the Alpha Board that, upon command from
the Main Processor on the Antares Board, selects the transceiver to be used. The signals from

14 | General information | Argus Radar System Operator Manual
the selected transceiver represent the data on which the equipment operates.
The signal process mainly consists of two steps:
• the Video Signal Processing
• the Automatic Target Tracking.
The results of the signal processing are both visualised on the monitor and sent to the Auto-
matic Target Tracking circuits.
Target and data display
The monitor presentation area is subdivided in a radar video presentation called PPI AREA
and a data table SYSTEM DATA AREA (for more details, refer to Chapter 2). The total area of
the screen is made up of a rectangle of pixels, depending on the size of the display. The video
signal and the graphic symbols (vectors, arcs, special symbols, bearing scale and segments)
are represented within the area of the PPI.
Video signal processing
This section receives the Video Signal from the transceiver and, after conversion into digital
form, processes it by removing:
• Sea Clutter
• Rain Clutter
• Interference.
The processed signal is sent to:
• the monitor for visualisation
• the Automatic Target Tracking circuits.
In the Video Signal Processing blocks, the digital signal is processed by means of complex
algorithms in order to recognise the presence of a target and, if the target is present, its shape
and the target coordinates.
The target coordinates and the target shape are sent, in digital form, to the Automatic Track-
ing Section of the equipment.
Failure procedure
This description does not describe failures that can occur during operation. If a failure occurs,
the operator must perform all relevant actions in order to remove the failure itself. When a
failure occurs, the fail condition is pointed out by:
• the red SYSTEM FAIL LED
• the acoustic alarm
• the Fail System Warning will be displayed in the General Purpose Section.
Watchdog function
Warning: The equipment’s operational software is monitorised by a hardware watch-
dog with a 3s timeout.
Non recoverable errors due to hardware faults are indicated by FAIL indication on the Control
Panel flashing at approximately 1 Hz.
Any type of failure caused by software or hardware, which stops the system for more than half
a second activates the System Failure relay on the Alpha PCB. This check doesn’t need soft-
ware intervention, but is automatically controlled by the hardware. The Failure relay contact
is normally closed, so the function is active, also when the main line is absent or the power
supply has failed.

• IMO-Resolution A.278 (VIII), A.694 (17), A.823 (19), MSC 191 (79), MSC 192 (79)
• EN 62388 Ed.2.0, 2013
• EN 62288 Ed.2.0, 2014
• EN 60945 Ed.4.0, 2002 incl. Corr.1, 2008
• EN 61162-1 Ed.4.0, 2010
• EN 61162-2 Ed.1.0, 1999
The ARGUS Radar is composed of the scanner unit and three modules i.e. a desk-mounted Monitor Cabinet, Keyboard and
Core Unit. Thanks to the modular design, it can be assembled to form a stand-alone display cabinet or may be flushmount-
ed into a mechanical bridge console. The standard basic configuration always includes an electronic, built-in Interswitch for
dual radar installation.
The above flexibility makes the ARGUS Radar the optimum solution for a dual radar system on new constructions and retro-
fit installations.

Warning: Highest mast position is good for long range detection, but it heavily affects
the detection in sea clutter. For optimal detection in sea clutter, suggested antenna height
from sea level is around 20 m. Usually the contradictory specifications are solved with
installation of more than one antenna, e.g. one at 30 m for long range detection and one
at 20 m for optimal detection of low intensity echoes in sea clutter. THe S-band transceiver
is always the optimal choice for reducing rain clutter reflections and increase long range
detection. Longer antennas for X-band are less susceptible to rain and sea clutter.
Warning: According to IMO standard, a ground speed sensor is required to be con-
nected to the Argus console. Only electronic positioning systems (EPFS) approved in ac-
cordance whit the requirement of the IMO in resolution msc.112(73) shall be connected to
the radar console.
It is allowed to use an electronic position fixing system (EPFS) approved in accordance with
the requirements of the IMO in resolution msc.112(73) or an alternative two dimensional
ground stabilising SDME in compliance with IMO resolution msc.96(72).
Warning: Only electronic positioning systems (EPFS) approved in accordance with the
requirements of the IMO in resolution msc.112(73) shall be connected to the radar console.
Warning: The radar unit is provided with a safety switch, which disable the antenna
movement during maintenance operations and avoids high voltage damage. Always turn
the safety switch off, whenever advised in this manual (for instance, before performing any
maintenance or installation procedures). Ignoring safety switch operation may produce
hazard of electrocution as well as other severe injures.
