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

![Radar image source configuration window](images/Asterix_1.png)

| No. | Element | Description |
|---|---------|----------|
| **1** | **Settings tree** | Hierarchical structure of the Asterix protocol 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 |

##### Primary settings

![Primary settings](images/Asterix_2.png)

| 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](images/Asterix_3.png)

| 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.
```

##### Network settings

![Network settings](images/Asterix_4.png)

```{hint}
Transport protocol for Asterix — UDP.
```

| No. | Element | Description |
|---|---------|----------|
| **1** | **Video Port No** | UDP port number from which the video stream is transmitted |
| **8** | **Reconnect** | Force device reconnection after entering the port number |

##### Monitor

Diagnostics of output parameters and device status during configuration.

![Monitor](images/Asterix_5.3.png)

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

##### Oscillogramm

An additional window that opens/closes by pressing the button of the same name in the **Radar** settings section. Allows visual monitoring of radar signal parameters.
