#### Network Radar Configuration

```{important}
The description of the radar image source configuration is of a general nature. The ONWA network radar is used as an example. Configuration must be performed by a specialist with the appropriate technical knowledge, skills, and qualifications who has completed training with the ECDIS manufacturer.

Configuration of radar models implemented in the ECDIS software is described in the installation documentation.
```

```{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 |
|-------------|
| {{ menu }} → {{ settings }} → Radar → Settings |

![Radar image source configuration window](images/Radar_Miran_0.png)

| No. | Element | Description |
|---|---------|----------|
| **1** | **Settings tree** | Hierarchical structure of the radar image source configuration sections |
| **2** | **Oscillogramm** | Signal oscillograms |
| **3** | Return to Radar list | Button to return to the list of all connected radar image sources |

2. **Network settings:**
   - Set the network connection parameters of the network Radar
   - Apply network settings — click **Apply**
   - Click **Reconnect**

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

```{note}
ECDIS contains the default settings of the ONWA Radar manufacturer. If necessary, modify the connection settings.
```

```{tip}
When configuring network parameters, verify:
- Correctness of the radar image source IP address (must match the radar processor settings)
- Network connection between ECDIS and the radar image 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** | Data, status, settings, and state of the video stream |
| **7** | **Control Channel** | Data, status, settings, and state of the control channel |
| **8** | **Status 1** | Data and status of the **radar image** transmission port |
| **9** | **Status 2** | Data and status of the parametric information transmission port |
| **10** | **Apply** | Apply the configured settings |
| **11** | **Reconnect** | Force device reconnection |

3. **Alignments. Antenna position**

![Antenna position alignment](images/Radar_Miran_4.png)

| No. | Parameter | Description |
|---|----------|----------|
| **1** | **Source coordinates** | Set the Radar antenna coordinates |
| **2** | **Source position** | Antenna installation point on the vessel diagram |
| **3** | **Range adjustment** | Distance correction — alignment of ENC and **radar image** |
| **4** | **Bearing adjustment** | Bearing correction — alignment of ENC and **radar image** |

```{important}
**Critically 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 configuration of the radar image 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.

It is impossible to compensate for not accounting for the GNSS antenna position through antenna alignment.
```

5. **Primary settings**

![Primary settings](images/Radar_Miran_2.png)

| No. | Parameter | Description |
|---|----------|----------|
| **1** | **Hardware** | Manufacturer name |
| **2** | **Name** | Radar name — entered during installation |
| **3** | **Transmit** | Radar scanner transmission indicator |
| **4** | **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. The displayed **radar image** cannot exceed the range set on the Radar control panel. |
| **5** | **Transparency** | **Radar image** transparency adjustment |
| **6** | **Brightness** | **Radar image** brightness adjustment |
| **7** | **Contrast** | **Radar image** contrast adjustment |
| **8** | **Master** | Master — always enabled. Control is not available. |
| **9** | **Signal adjustment** | Indication of the Radar control panel settings. Adjustment from ECDIS is not available. |
| **10** | **Radar control** | Indication of statuses set on the Radar control panel. Control from ECDIS is not available. |

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

8. **Monitor** — diagnostics of output parameters and device status during configuration.

![Monitor](images/Radar_Miran_5.png)

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

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