Raymarine - QUANTUM 2
The QUANTUM 2 CHIRP pulse compression radar from Raymarine with Doppler collision avoidance technology offers you exceptional safety over long as well as extremely short distances.
Thanks to the special processing of the Doppler radar data, moving targets can be displayed in color on the screen.
Identify potential targets easily
Raymarine's QUANTUM-2 Doppler target processing ensures that moving radar contacts are color-coded. This makes it immediately clear at a glance whether the target is approaching or moving away. This results in a reduced risk of collision.
Superior collision avoidance
Doppler-enabled MARPA offers effortless tracking of dangerous targets by eliminating the need to set up guard zones. Raymarine MARPA target tracking uses the same proven technology also used by the US Coast Guard.
Key features:
- The Doppler display for moving targets provides excellent situational awareness at a glance
- Fully automatic ARPA target tracking together with manual MARPA mode
- Adjustable True Trails target history shows the movement path of moving contacts
- CHIRP pulse compression detects contacts at distances as close as 18 feet when navigating in zero visibility
- 24-mile range for early detection of traffic, navigational aids, landfall and weather
- Instant-on detection – QUANTUM starts up and is ready for operation within seconds
- Excellent interference rejection eliminates noise from other radar units
- Simplified installation with Wi-Fi
- Easy upgrade – QUANTUM 2 fits the same bolt pattern as other Raymarine radar antennas
- Lightweight and easy to install – QUANTUM weighs up to 50 % less than comparable magnetron radars
- Safe emissions – QUANTUM can be mounted anywhere on board
- Low power consumption for longer battery life under sail
How does Doppler radar work?
Microwave energy waves are reflected by a distant target, just like conventional radar.
Moving targets send back echoes whose frequencies shift upward or downward from the original transmission.
For approaching targets, the frequency increases because the leading edge of the reflected echoes is received more frequently as the target range decreases.
For receding targets, the frequency decreases because the reflected echo spreads out as the range increases.
Doppler radar units are designed to detect these small changes in wave frequency in order to define moving radar targets.
Doppler radar is specifically tuned to distinguish frequency shifts in the radar echo. This makes it possible to differentiate a moving target from a stationary one based on the reflected echo. Clear color codes then indicate whether they are approaching or moving away.
Incoming targets are marked red.
Outgoing targets are green.
The use of color codes makes it easy to distinguish moving traffic from other stationary targets such as land, navigational aids or stationary/anchored vessels.

Fully automatic target acquisition and tracking
QUANTUM 2 also features fully automatic target acquisition and tracking. Configure custom safety and alarm zones and be warned of new radar contacts entering the zone.
QUANTUM 2 automatically begins tracking these contacts, calculating their course, speed, Closest Point of Approach (CPA), and more. You are warned of dangerous targets by audible alarms and easy-to-understand on-screen graphics.
QUANTUM 2 features Raymarine's new True-Trails target history display. With the True-Trails functions, you can see the trail of the „wake" behind each moving target. This additional information makes it even easier to navigate in heavy traffic environments, interpret the movement of other vessels, and make smart navigation decisions for safe passing.
QUANTUM 2 has very low power consumption, making it particularly attractive for vessels operating exclusively on battery power. QUANTUM 2 with Doppler radar can be installed using a traditional cable configuration or connected to your Raymarine MFD via integrated Wi-Fi technology.
