Radar Integrator Board

General Description
The Radar Integrator board (RIB) is a module operating in combination with an IBM PC
compatible computer to enhance functional capabilities of the ECDIS system.
The Radar Integrator board is designed for the reception of analog video signals
from the radar and their processing. The RIB enables the automatic detection,
automatic acquisition and automatic tracking of targets, calculations of targets
coordinates and motion parameters and on-line transmission of this data to
the ECDIS system as well as the formation of a radar picture to be displayed in
combination with an electronic chart.

Purposes

Input of Radar Signals
•
Analog/digital conversion of radar signals;
•
Reception of information on the course and speed.
Selection of Radar Targets
•
Suppression of sea clutter, interference from operating radars and other
occasional clutter;
•
Detection of radar echoes with an adaptive threshold;
•
Selection of objects by size out of the set range of values;
•
Determining of targets’ gravity centers and measurement of their coordinates;
•
Automatic acquisition and automatic tracking of targets.
Note: The criterion for selecting targets for tracking is the availability; in several
consecutive scans, of an echo with a higher intensity as compared to
the background within a spatial locality fitting the set range in size and
discrimination.
•
Automatic assigning of names to new targets;
•
Determining of the targets’ current courses and speeds;
•
Recording of target loss time;
•
Computation, preparation, and transmission to the Navi-Sailor series systems of
all the tracked targets’ data cards including the following parameters:
– Number or name assigned to the target;
– Target status or type:
New target;
Steadily tracked target;
Target not observed;
Target lost.
– Target’s range (in nautical miles);
– Target’s true bearing (in degrees);
– Target’s relative course (in degrees);
– Target’s relative speed (in knots);
– Target’s true course (in degrees);
– Target’s true speed (in knots).
