Configuring a Radar with Asterix Protocol Support

Important

The description of the radar image source configuration is of a general nature.

For correct operation of the radar image source, configuration must be performed by a specialist with the appropriate technical knowledge and skills who has completed training with the ECDIS manufacturer.

Warning

Incorrect configuration of the radar image source may result in incorrect display of the radar image on the chart and an erroneous assessment of the navigational situation.

Source configuration:

Menu path

MenuSettings → Radar → Settings

Radar image source configuration window

No.

Description

1

Settings tree

Hierarchical structure of the Asterix protocol radar image source configuration sections

2

Oscillogramm

3

Return to Radar list

Button to return to the list of all connected radar image sources

Primary settings

No.

Parameter

Description

1

Hardware

Equipment name

2

Name

Radar name — entered during installation

3

Radar image range

Select the radar image display range. Does not change the range on the Radar. When the radar image range is increased, the radius of the displayed image increases.

4

Signal adjustment

Signal adjustment, surface and precipitation clutter compensation, and overall gain (depends on equipment implementation)

5

IR

Interference rejection

6

Transparency

Radar image transparency adjustment

7

Brightness

Radar image brightness adjustment

8

Contrast

Radar image contrast adjustment

9

Frequency redraw

Radar image refresh rate on screen, in Hertz

10

Dead zone

Dead zone radius adjustment

Note

Display parameters may vary depending on navigation conditions (open sea, coastal zone, narrow waters). Save optimal settings for different operating conditions.

Alignments. Antenna position

Antenna position alignment

No.

Parameter

Description

1

Radar antenna position

Radar antenna coordinates relative to CCRP

2

Range Adjustment

Range correction. Determination and compensation of the range correction is performed using a distant point object

3

Bearing Adjustment

Bearing correction. Determination and compensation of the correction is performed using a distant point reference

Important

Incorrect antenna position alignment causes displacement of the radar image relative to the chart, which may create a dangerous navigational situation. Alignment verification and correction must be performed:

  • During initial configuration of the radar image source

  • Before each voyage departure

  • After repair work on the radar antenna

  • When systematic discrepancies between the radar image and chart information are detected

  • At least once a month during operation

Blank sector

When operating with a Radar, the Blank sector activates sectors within which the antenna’s high-power transmission is disabled.

No.

Parameter

Description

4

Enable blank sector

Enable the sector (depending on the radar model, two sectors may be supported)

5

Start

Sector start angle

6

Width

Sector width

Note

If the equipment (radar) does not support Blank sector configuration from external devices, the sectors can be used to mask interference sectors. In this case, during primary signal processing, the specified sectors are excluded from processing and display.
