RPU-1.3 Radar Processor Configuration
Important
The description of the radar image source configuration is of a general nature. The RPU-1.3 radar processor model is used as an example. 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.
Configuration of radar processor 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.

Network settings:
Set the IP address of the radar image source device
Set the data/control ports in accordance with the documentation
Click Reconnect
If configured correctly, the connection statuses in the information group (4) will change and the data packet counters will update.
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

Radar signals settings: set the mode in the Signal source dropdown list. By default, this parameter is set to standard (RPU-1.3). If all parameters are configured correctly and the radar image layer is enabled in Operational settings — see 3.8, the radar image will appear on the screen, and a Diagnostic group with information about the selected device’s status will be displayed in the settings window.

Alignments. Antenna position: set the radar antenna coordinates relative to CCRP. If there is a discrepancy between the radar image and chart information, enter distance and angle corrections. It is recommended to perform these settings regularly.
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 initial 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
If a discrepancy between the radar image and the chart is detected, immediate verification and correction of the alignment is required. Continued use of an incorrectly configured radar image source is hazardous to navigation.
Primary settings: enter the source name (1), set the required range scale. Using the controls and Gain, Sea, Rain parameters, adjust the signal detection thresholds. If necessary, use the Auto switches to enable automatic sea clutter suppression functions. Depending on the display model, adjust the display parameters so that the radar image is clearly visible on the screen.
Tip
Recommendations for display parameter configuration:
Gain: start with automatic mode; if necessary, adjust manually for optimal target display
Sea: this setting is especially important when navigating in rough sea conditions to suppress wave clutter
Rain: use during heavy precipitation to improve target visibility in rainy weather
Automatic modes: recommended for standard conditions; manual adjustment — for specific conditions
Note
Display parameters may vary depending on navigation conditions (open sea, coastal zone, narrow waters). Save optimal settings for different operating conditions.
Filtering: configure Noise interference suppression settings, set the parameters for the automatic Auto Gain and Auto Sea modes if they are enabled (see the item above).
Composite signal: configuration is performed when using a radar station that transmits radar data via a composite video channel. Configuration parameters depend on the type and model of the radar station used.
Monitor — diagnostics of output parameters and device status during configuration.
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.
