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 monit
ors 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.
