- Raymarine Quantum2 Doppler Radar

Raymarine – QUANTUM 2 Doppler

The Raymarine QUANTUM 2 CHIRP Pulse Compression radar with Doppler target detection technology offers you added safety at both long and short ranges.
Thanks to the special processing of Doppler radar data, it is possible to display moving targets in colour on the screen.

Easily identify dangerous targets

Raymarine Quantum 2 Doppler target processing detects and colour codes moving radar contacts for instant recognition and reduced collision risk.

Excellent collision avoidance

The Quantum 2 MARPA mode offers an effective tool for tracking dangerous targets. Raymarine MARPA target tracking uses the same technology that is trusted by the United States Coast Guard.

Key features

Doppler imaging of a moving target allows for excellent situational awareness at a glance
Fully automatic ARPA target tracking with manual MARPA mode
The adjustable TrueTrails target history shows the movement history of moving contacts.
CHIRP pulse compression detects contacts up to 5.5 metres away to enable navigation in zero visibility.
24-mile range for early detection of traffic, navigation aids, landing, and weather
Instant awareness – Quantum boots up and is ready to use in seconds
Excellent interference rejection eliminates noise from other radars
Simplified installation via Wi-Fi or thin-wire network connection
Easy upgrade – Quantum 2 fits the same bolt pattern as other Raymarine scanners
Lightweight and easy to install – the Quantum weighs up to 50% less than comparable magnetron-based radars
Low emissions – install Quantum anywhere on board
Low energy consumption extends battery life while sailing

Kuidas Doppler töötab?

Microwave energy waves are reflected back from a distant target, just like with a normal radar.
Moving targets return echoes whose frequencies are shifted up or down from the originally transmitted frequency.
For incoming targets, the frequency increases as the leading edge of the returning echoes is received more frequently as the target's range decreases.

For receding targets, the frequency drops as the range of returning echoes increases and they spread out more widely.

Doppler radars are designed to detect these tiny frequency shifts and use them for classifying moving radar targets. Doppler radar is specifically tuned to detect the radar echo frequency shift generated by moving and stationary targets.

The Quantum 2 then encodes the moving targets with unique colours to show if they are approaching or moving away. Incoming targets are red.
Outgoing targets are green. Colour-coded targets distinguish moving traffic from other stationary targets, such as land, navigational aids or stopped/anchored vessels.

Fully automatic target detection and tracking

The Quantum 2 radar offers fully automatic target detection and tracking. You can set up custom safety or exclusion zones and receive notifications of new radar contacts entering the zone. Quantum 2 will automatically start tracking these contacts, calculating their course, speed, closest point of approach, and more. Dangerous contacts will be alerted to you with audible alarms and easy-to-understand on-screen graphics.

The Quantum 2-l is Raymarine's new True Trails target history display. The True Trails function allows you to see the historical „trail“ behind every moving contact. This additional information makes it even easier to interpret the movements of other vessels and make smart manoeuvring decisions for safe overtaking.

Like all Raymarine Quantum systems, this one has a rugged and lightweight design that is extremely simple to install. The Quantum 2's power consumption is very low, making it particularly well-suited for boats that operate solely on battery power. With Doppler, the Quantum 2 can be installed as a traditional wired configuration or use its built-in WiFi technology to connect to your Raymarine MFD.
