Marine Radar Scanners and Antennas

Marine Radar Scanners | Raymarine by FLIR

Day and night systems from Raymarine keep you aware of surrounding traffic, hazards, rain sea birds and much more. From compact and lightwight digital radomes, to ultra-high performance Super HD Colour open arrays, Raymarine has the perfect radar solution for every boat.



Raymarine has 3 different types of radar antenna:

CHIRP Pulse Compression

(Quantum & Quantum 2 Radar)

HD Color Technology

(HD Color Radomes)

Super High Defintion Radar Technology

(Open Array Scanners)

Raymarine Radar Delivers Unmatched Performance and Ease-of-Use

Raymarine's HD Colour technology brings radar users the power of digital signal processing with a truly adaptive transmitter and receiver that automatically adjusts to changing environmental and sea conditions.

Raymarine Radar - Weather Advantage | Raymarine by FLIR

Weather advantage

Raymarine's HD Colour scanners provide superior all weather performance allowing you to still see targets through rain and thunderstorms. Use radar to track weather too.

During this abnormally heavy rain storm (see left hand image), rain mode was used to cut the clutter to clearly reveal the targets (see right hand image).

Cut the clutter

Detect targets at very close proximity to your vessel, or at very long ranges to see distant vessels, land features and even weather fronts. Distinguish targets through even the heaviest rain clutter.

Use the radar to see the weather coming, then use the radar overlay to map the weather pattern onto the chart.

Track Targets

Not everything transmits AIS!

Using MARPA* (mini-automatic radar plotting aid) allows you to identify vessel, speed, bearing, closest point of approach (CPA) and time to closest point of approach (TCPA), dangerous/proximity alarms, overlay AIS info for further target clarification.

*For the best radar overlay and MARPA performance fit an Smart Heading Sensor or an Evolution Autopilot course computer.

Raymarine Radar - Track Targets 1 | Raymarine by FLIR

Target (1) has been aquired (red circle overlay) using MARPA and is being tracked by your radar. Speed and bearing of the target are shown and the target's heading is shown as a thin red line at 65º (2).

Raymarine Radar - Track Targets 2 | Raymarine by FLIR

The tracked target has now moved into the previously set guard zone around your vessel and has triggered the dangerous target alarm, seen on screen, and set off an audible alarm.

Raymarine Radar - Track Targets 3 | Raymarine by FLIR

The alarm has been acknowledged and the target's (1) (now overlaid with a red triangle to note possible danger) closest point of approach (CPA) to your vessel is shown on screen as 0.376nm (3) and time to closest point of approach (TCPA) is 4 mins 20 secs (2).

Radome or Open Array Radar Antenna?

When building a Raymarine Radar System you have your choice of either Open Array or Closed Radome scanner. Both Radomes and Open Arrays are fully compatible with every multifunction display and deliver unparalleled performance.

Digital, HD Colour, Super HD Colour Radar - What's The Difference?

Marine Radar Colour Resolutions - Digital Radar | Raymarine by FLIR

Digital Radar

Offers 4kW capability for improved performance and uses digital processing for increased target definition. Digital reduces the cable size (compared to analogue) and makes an easier interface to larger systems.

Available models: Digital Radome

HD Color Radar

Raymarine's HD Colour radar utlises powerful signal processing technologies that help distinguish between target types, detects weak and distant contacts automatically, while virtually eliminating clutter and noise. The truly adaptive transmitter and receiver automatically adjusts to changing environmental and sea conditions. HD Colour radar delivers a dramatically clearer radar picture with crisp, well-defined contact echoes and a life-like target presentation.

Available models: HD Colour Radome and HD Colour Open Array

Super HD Colour Radar

Super HD Colour radar is a giant leap in leisure marine radar. Using highly advanced digital signal processing, Super HD Colour radar has much greater dynamic range than conventional radar enabling the digital receiver to acquire and process vast amounts of echo information that is normally lost by conventional analogue radar systems. Super HD Color technology intelligently isolates and identifies true radar targets, while simultaneously eliminating unwanted clutter. The extra-narrow beam width pinpoints targets with stunning clarity. The result is a dramatically clearer radar display.

Available models: Super HD Colour Open Array

Marine Radar Colour Resolutions - Digital vs HD Colour | Raymarine by FLIR

Digital vs HD Colour

HD Colour targets are clearly defined compared to the standard Digital image.

Marine Radar Colour Resolutions - HD Colour vs Super HD Colour | Raymarine by FLIR

HD Colour vs Super HD Colour

Super HD Colour reveals even more detail than HD Colour. The Super HD Colour image shows that there are actually two targets in the ringed area, whereas the same targets on the HD image appear as one.
