Configuring the MIRAN 09 Network Radar

Important

Configuration of the MIRAN 09 network Radar. Configuration must be performed by a specialist with the appropriate technical knowledge, skills, and qualifications who has been trained by the ECDIS manufacturer.

Warning

Incorrect configuration of the MIRAN 09 Radar may result in incorrect display of the radar image on the chart and erroneous assessment of the navigational situation.

Source configuration:

Menu path
→ → Radar → Settings

No.	Element	Description
1	Settings tree	Hierarchical structure of radar source configuration sections
2	Oscillogram	Signal waveforms
3	Return to Radar list	Button to return to the list of all connected radar sources

2. Network settings:

   • Set the network connection parameters for the network Radar

   • Apply network settings – press Apply

   • Press Reconnect

   If configured correctly, the connection statuses in the information group (4) will change and the data packet counters will update.

Note

ECDIS contains default settings from the ONWA Radar manufacturer. Modify the connection settings if necessary.

Tip

When configuring network parameters, verify:

• Correct IP address of the radar source (must match the radar processor settings)

• Network connection between ECDIS and the radar source

• Absence of port conflicts with other systems

• Stability of data packet counters — they should continuously increase when the source is active

No.	Element	Description
1	MAC	Radar MAC address
2	IP	Radar network address
3	Master	Network address of the Radar control device
4	Gate	Network gateway
5	Mask	Subnet mask
6	Video data	Video stream data, status, settings, and state
7	Control Channel	Control channel data, status, settings, and state
8	Status 1	Radar image transmission port data and status
9	Status 2	Parametric data transmission port data and status
10	Apply	Apply the current settings
11	Reconnect	Force device reconnection

3. Alignments. Antenna position

No.	Parameter	Description
1	Antenna coordinates	Set the Radar antenna coordinates
2	Antenna position	Antenna installation point on the vessel diagram
3	Distance alignment	Distance correction — superimposition of ENC and radar images
4	Bearing alignment	Bearing correction — superimposition of ENC and radar images
5	Blanking sector	Enables the antenna radiation blanking sector. In the blanking sector, the transceiver does not transmit a signal
6	Start	Start of the radiation blanking sector. Angle in the ship’s relative bearing system. Measured from the trigger position (arrow on the antenna housing), clockwise from 0 to 359 degrees
7	Width	Width of the radiation blanking sector, in degrees

Warning

It is recommended to verify the correctness of the Radar antenna alignment before each voyage.

Alignment is performed relative to a point-identified landmark, by matching the landmark echo in bearing and distance.

Important

Incorrect antenna 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:

• When configuring a radar source

• 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

Warning

For correct radar image overlay, the coordinates of the GNSS antenna(s) and the Radar antenna must be entered.

Compensating for the GNSS antenna position offset through antenna alignment is not possible.

5. Primary settings

No.	Parameter	Description
1	Equipment	Manufacturer name
2	Name	Radar name — entered during installation
3	Transmit	Radar scanner transmission indicator
4	Radar image display range	Select the radar image display distance. Changes the Radar range scale.
5	Transparency	Radar image transparency control
6	Brightness	Radar image brightness control
7	Contrast	Radar image contrast control
8	Master	Master — always enabled
9	Gain	Radar transceiver gain control
10	Sea clutter	Sea clutter compensation. Automatic adjustment can be enabled
11	Rain clutter	Precipitation clutter compensation (rain, snow, dense fog). Automatic adjustment can be enabled
12	Pulse	Pulse length control. Depending on the Radar model and the set range scale, the navigator may force-select the pulse type: long or short. Manually changing the pulse length is not recommended — this may cause damage to the Radar transceiver
13	Noise suppression	Forced noise suppression. Enables additional signal filtering in automatic mode
14	Interference rejection	Enables automatic suppression of asynchronous interference from the radar of an oncoming vessel
15	Echo stretching	Forms echoes on the screen by adding weaker target echoes. Increases the target RCS
16	Scan refresh rate	Radar image redraw frequency on the screen, in Hz

Note

Display parameters may vary depending on navigation conditions (open sea, coastal zone, narrow channels).

1. Monitor — diagnostics of output parameters and device status during operation configuration.

After successful connection and configuration, diagnostic information is displayed in the Monitor.

Oscillogram — an additional window that opens/closes by pressing a button in the Radar settings section. Allows visual monitoring of radar signal parameters.
