Marine Radar

NEW Quantum Radar | Radomes | Open Array Radar Antennas

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 Color open arrays, Raymarine has the perfect radar solution for every boat.


Setting a new standard for solid state marine radar, Quantum delivers superior radar imaging on both long and extremely short ranges. Integrated Wi-Fi make installation easy and Quantum’s energy efficient and lightweight design provides safe radiated emissions and reduced power consumption.

Raymarine Digital and HD Colour Radome Radar

Radome antennas are the perfect blend of compact size, light weight and high performance. Choose a radome antenna when space is a premium or restricted by rigging. Radome scanners also consume less power than open array scanners which is essential for long-distance cruising sailboats.

Raymarine HD Colour & Super HD Open Array Scanners

The choice of mid to large-sized powerboats and sailing vessels, open array radar scanners deliver higher sensitivity, better target detection and improved target separation. Open array systems are available with 4kW or 12kW transmitters for exceptional performance at all ranges.

Marine Radar Features

Raymarine radar delivers unmatched performance and ease-of-use
Raymarine's HD color 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.

Weather advantage

Raymarine's HD color 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 a smart heading sensor or an SPX autopilot course computer.

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).

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

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).

Digital, HD Color, Super HD Color Radar

Raymarine radar - What's the difference?


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 color radar utlizes 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 color radar delivers a dramatically clearer radar picture with crisp, well-defined contact echoes and a life-like target presentation.

Available models: HD color Radome and HD color Open Array

Digital vs HD color

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

HD color vs Super HD color

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

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.
