Furuno Radar Compatibility

TZ Coastal Monitoring is compatible with the 2 main Furuno Radar ranges:

NavNet UHF DRS

  • X band Radars

  • Antenna maximum size is 6ft (also available with 4kW Dome)

  • From 4kW to 25kW

Note This range can be directly connected to a PC running TZ Coastal Monitoring. This direct capability significantly reduces the hardware cost as no dedicated radar screen and/or processor is required (this will only require a specific « PSU » power supply).

FAR 2xx7 Range

  • X Band Radar / Up to 8ft Antenna / Up to 25kW

  • S Band Radar / Up to 12ft Antenna / Up to 60kW

Note In order to be interfaced to TZ Coastal Monitoring, this radar range requires a complete radar including dedicated processor, screen and keyboard.

A new Radar range is currently under development FAR3000

FAR3000 will use « SOLID STATE » Technology (no magnetron).

Radar Specifications

Radar resolution mainly comes from the antenna size. The bigger the antenna is, the higher the radar resolution will be and consequently the ARPA targets acquisition will be more accurate.

Example of difference between a 6ft antenna (at the top) and a 24 inch Dome (at the bottom)

The two others factors which strongly affect the radar coverage are:

  • its power: the higher the power is, the farther the microwaves will reach

  • the height of the antenna location: the higher the antenna is located the farther the microwaves will reach

Example: Whatever its power and height are, a radar will be able to detect a 10m height target at maximum of 15NM.

The curvature of the Earth prevents the radar to "see" farther.

Radar : Power Vs Ranges

FURUNO DRS4D (Dome) Detection Distance in NM
Detection of a small target (1 m ²) 1 NM
Detection of a medium size target (10m²) 2 NM
FURUNO DRS12A (6ft Antenna) Detection Distance in NM
Detection of a small target (1 m ²) 3 NM
Detection of a medium size target (10m²) 5 NM
FURUNO DRS25A (6ft antenna) Detection Distance in NM
Detection of a small target (1 m ²) 4 NM
Detection of a medium size target (10m²) 6 NM
FURUNO FAR2127 (8ft Antenna) Detection Distance in NM
Detection of a small target (1 m ²) 6 NM
Detection of a medium size target (10m²) 10 NM
FURUNO FAR2137 (12ft Antenna) S Band Detection Distance in NM
Detection of a small target (1 m ²) 7 NM
Detection of a medium size target (10m²) 12 NM

Note: The next « solid state » Furuno Radar range will certainly offer bigger coverage.

Target Types in m²:

  • Aids to Navigation without radar reflector < 1m²

  • Small Open Boat (Fiber Glass, Wood) with 2 persons and outboard: 1m² to 5m²

  • Small Sailing Boat and fishing vessels: 3m² to 10m²

  • Aids to Navigation with radar reflector > 10m²

  • Fishing Vessels, Patrol Vessels: 10m² to 100m²

  • Flock of Birds: up to 3m²

DRS DUAL RANGE feature

DRS range offers a very powerful (and patented) DUAL RANGE feature. This very advanced feature enables the radar to scan and display two different real time ranges at each antenna rotation. This allows keeping high short range resolution and long range detection with one single radar antenna.
