NEW Raymarine Quantum 2 CHIRP Radar with Doppler Collision Avoidance Technology

NEW - Quantum 2 CHIRP Radar with Doppler Collision Avoidance Technology  | Raymarine - A Brand by FLIR

Introducing Raymarine Quantum 2 Radar with Doppler collision avoidance technology. The Quantum 2 next generation CHIRP pulse compression radar by Raymarine provides superior target awareness at both long and extremely short ranges.

Using advanced Doppler processing, the system instantly highlights moving radar contacts and color codes them to indicate whether they are inbound or outbound. Quantum with Doppler makes it easy to discern potentially dangerous targets when navigating in high-traffic areas.

Easily Identify Dangerous Targets

Raymarine Quantum 2 Doppler target processing readily identifies and color codes moving radar contacts for instant recognition and reduced risk of collision.

Safer Navigation

Quantum 2’s exclusive Safety Sector feature provides the maximum level of visibility to dangerous targets in the path of your vessel (both mobile and stationary).

Superior Collision Avoidance

Doppler-enabled MARPA provides an effortless means of dangerous target tracking by eliminating the need to setup guard zones. Raymarine MARPA target tracking is the same technology trusted by the United States Coast Guard.

Microwave energy waves are bounced off of a distant target, just like conventional radar.

Moving targets send back echoes whose frequencies shift upward or downward from what was originally transmitted.

For inbound targets, the frequency increases as the leading edge of the returning echoes are received more frequently as the target’s range decreases.

For outbound targets, the frequency drops as the returning echoes spread out as its range increases.

Doppler radars are engineered to detect these small shifts in wave frequency, and use them to classify moving radar targets.

Quantum 2 - Target Processing | Raymarine - A Brand by FLIR


Doppler radar is tuned specifically to detect the radar echo frequency shift returned by moving vs. stationary targets.

Quantum 2 then uniquely color codes moving targets to indicate whether they are getting closer, or moving away.

  • Inbound targets are colored red.
  • Outbound targets are colored green.

Color coded targets make it simple to pick out moving traffic from other stationary targets like land, navigation aids or stopped/anchored vessels.


Doppler does an excellent job of bringing attention to moving targets, but it does downplay stationary targets, that can be equally as dangerous.

Safety Sector provides equal attention to these imminent threats by coloring them as inbound targets. Potential targets include:

  • Buoys.
  • Exposed Hazard (rocks, pilings, etc).
  • Slow moving, low visibility vessels.

Quantum 2's Safety Sector spreads 15° from the bow to a distance of approximately 200m.

NOTE: The safety sector is not visible on the display. Quantum 2 automatically processes and highlights targets within this region in red.

The Quantum 2 also features fully automatic target acquisition and tracking. Configure custom safety or alarm zones and be alerted to new radar contacts entering the zone. Quantum 2 can begin tracking those contacts automatically, calculating their course, speed, closest point of approach and more. You’ll be alerted to dangerous contacts with audible alerts and easy to understand on-screen graphics.

Quantum 2 also features Raymarine’s new True Trails target history display. The True Trails features enables you to see a historical “wake” behind every moving contact. This additional information makes it even easier to interpret the motion of other vessels, and make smart maneuvering decisions to pass safely.

Quantum 2 - Rugged and LightWeight Design | Raymarine - A Brand by FLIR

Like every Raymarine Quantum system, you’ll also benefit from a rugged and lightweight design that is super-easy to install. Quantum 2 has very low power consumption making it especially friendly to vessels running exclusively on battery power. Quantum 2 with Doppler can be installed in a traditional wired configuration, or use its built-in Wi-Fi technology to connect it to your Raymarine MFD.

The Quantum 2 with Doppler truly sets the standard for on the water safety and collision avoidance.
