Introducing Raymarine Quantum 2 radar with Doppler collision avoidance technology. Raymarine's next-generation Quantum 2 CHIRP pulse compression radar improves target detection at both long and very short ranges.
Using advanced Doppler processing, the system instantly highlights radar contacts and color-codes them to indicate whether they are approaching or receding. Quantum with Doppler helps you distinguish potentially dangerous objects when navigating high-traffic areas.
Main features Doppler display of moving target allows for greater situational awareness at a glance
Fully automatic ARPA target tracking, plus manual MARPA mode
Adjustable TrueTrails target history shows the movement history of moving contacts
CHIRP pulse compression detects contacts from at least 5 meters away while cruising in zero visibility
24-mile range for early detection of traffic, navigation aids, landfalls and weather conditions
Instant awareness: Quantum boots up and is ready to use in seconds
Excellent interference rejection eliminates noise caused by radar transmissions from other vessels
Easy installation with Wi-Fi or thin-wired network connectivity
Easy to upgrade: Quantum 2 uses the same bolt pattern as other Raymarine scanners
Lightweight and easy to install: Quantum weighs up to 50% less than similar magnetron radars

Low power consumption for longer battery life when sailing
Easily identify dangerous targets 
Raymarine Quantum 2 Doppler target processing easily identifies and color-codes radar contacts, allowing you to instantly recognize them and reduce the risk of collision.
TARGET DOPPLER PROCESSING Doppler radar is specifically tuned to detect the frequency change of echoes returned by moving and stationary targets.
The Quantum 2 then color-codes moving targets to indicate whether they are approaching or receding.
Approaching targets are colored red.
Receding targets are colored green.
Color-coded targets make it easy to identify moving traffic among other stationary targets such as land, navigational aids, and stationary or anchored vessels.
AUTOMATIC TARGET ACQUISITION AND TRACKING The Quantum 2 acquires and tracks targets completely automatically. You can configure safety or warning zones and receive alerts for new radar contacts entering them. The Quantum 2 automatically begins tracking these contacts and calculates their course, speed, closest approach point, and more. Dangerous contacts are reported with audible warnings and easy-to-understand on-screen graphics.
The Quantum 2 also features Raymarine's new True Trails historical display. True Trails allows you to see a historical "wake" behind each moving target. This additional information makes it even easier to interpret the movements of other vessels and make intelligent maneuvering decisions to safely pass.
HOW DOPPLER RADAR WORKS Microwave energy bounces off a distant target, just like in conventional radar.
Moving targets return an echo whose frequency is higher or lower than what was originally transmitted.
For approaching targets the frequency increases, since the rising edge of the returning echoes is received more frequently as the distance to the target decreases.
For receding targets, the frequency decreases, as the returning echoes become more evenly distributed as the distance increases.
Doppler radars are designed to detect these small changes in wave frequency and use them to classify moving targets.
