Dual Radar

This chapter only applies to TZ Coastal Monitoring Dual Radar when the two radars are connected locally to the computer. If you are using TZ Coastal Monitoring Remote (radars that are remotely connected using the Client/Server architecture), please refer to the Remote Radars chapter.

TZ Coastal Monitoring Dual Radar allows you to connect two Furuno radars directly to a single computer. The two radar antenna images are merged onto the chart for seamless integration, providing continuous coverage.

Important Limitations:

A TZ Coastal Monitoring Dual Radar system has several restrictions:

- No Dual Range on DRS: When using two DRS radars, the Dual Range feature of each radar is unavailable. In other words, each antenna can only display one range (“picture”) at a time.

- Master Radar Dependency: When two antennas are connected, the one configured as the First Radar in the Radar Options acts as the Master for network management. If the Master radar fails, the second antenna will also stop working in the Dual Radar setup.

- Same Radar Family Required: Both antennas must be from the same radar family (mixing FAR and DRS antennas is not supported).

- Linked Transmission Control: The two antennas cannot be set to TX or STBY independently—both must be in the same mode simultaneously.

Because of these limitations, the TZ Coastal Monitoring Dual Radar is best suited for applications where two radars operate as a single, integrated system. A typical example is an offshore oil platform that requires two radars to achieve full 360° coverage around the structure. This configuration is not suitable when radars are far apart or require independent control. In such cases, it is recommended to use multiple TZ Coastal Monitoring Single Radar systems combined within a TZ Coastal Monitoring Remote setup.

Note: Please refer to the Dual Radar Setup for important setup instructions.

Radar WorkSpace

When selecting the "Radar" WorkSpace, the radar that you want to display can be selected from the "Radar" button located in the Ribbons under "Radar Source":

Note: When using a WorkSpace with multiple Radar windows, the Radar Source selection applies to the window which is selected (surrounded by a yellow border).

Each "Radar" WorkSpace will remember its own Radar Source selection.

Radar Overlay

The Radar Overlay on the chart can be turned ON from the Radar button located in the Ribbons. This will automatically transmit both Radars and display them on the screen. The Radar echo are automatically merged.

From the "Monitoring" WorkSpace, you can adjust the Active Radar using the Radar NavData. The Active Radar Nickname is indicated inside the Radar NavData (title) or by putting the cursor over the Radar Range indication (in the lower right of the screen). It is possible to switch the Active Radar selection by clicking on the Radar NavData switch icon or by clicking on the Radar icon that are marked on the chart:

When switching the Active Radar, the range scale and the Radar NavData will automatically switch values to reflect the Active Radar parameters.

Note that the Active Radar rings and icon are displayed in red on the chart:

Note: To change the Range of the Active Radar from the chart, you can add the "Range In" and "Range Out" tools in the Toolbar.

There are two Radar Overlay display modes that can be selected from the Radar Options under "Radar Fusion":

  • Exclusive (default): This setting should be the best choice for most applications. In areas where both radars overlap, only one radar will be displayed (one radar has priority over the other). The radar that gains priority in the overlapping area is the radar with the smallest range (usually the radar with the best echo resolution). This setting also takes into account the blank sector and properly fills the gap when needed.

  • Merge: Both radar pictures are merged (displayed on top of each other) in overlapping areas. This setting should be used when the radars are not overlapping.

IMPORTANT: Both Radars have to be turned ON at the same time. It is NOT possible to operate one radar without the other.
