Raymarine Quantum 2 CHIRP Doppler RadarUsing advanced Doppler processing, the system instantly highlights moving radar contacts and color codes them to indicate whether they are inbound or outbound. The Quantum 2 Doppler Radar makes it easy to discern potentially dangerous targets when navigating in high-traffic areas.
Easily identify dangerous targetsRaymarine Quantum 2 Doppler target processing readily identifies and color codes moving radar contacts for instant recognition and reduced risk of collision.
Superior collision avoidanceQuantum 2 MARPA mode provides an effective means of dangerous target tracking. Raymarine MARPA target tracking is the same technology trusted by the United States Coast Guard.
Super-easy to install and lightweight designQuantum 2 has very low power consumption and it can be installed in a traditional wired configuration, or use its built-in Wi-Fi technology to connect it to your Raymarine MFD.
Raymarine Quantum 2 CHIRP Doppler Radar features
- Doppler moving target display allows for superior situational awareness at-a-glance
- Fully automatic ARPA target tracking, along with manual MARPA mode
- Adjustable TrueTrails target history shows the motion history of moving contacts
- CHIRP Pulse Compression detects contacts as close as 18-feet for zero-visibility navigation
- 24-mile range for early detection of traffic, navigation aids, landfall and weather
- Immediate awareness – Quantum starts up and is ready to go in seconds
- Superior interference rejection eliminates noise from other radars
- Simplified installation with Wi-Fi or thin wire network connectivity
- Easy upgrade – Quantum 2 fits the same bolt pattern as other Raymarine scanners
- Lightweight and easy to install – Quantum weighs up to 50% less than comparable magnetron radars
- Safe emissions – mount Quantum anywhere onboard
- Low power consumption for extended battery life under sail
How Doppler radar works?
- 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.
Automatic target acquisition and trackingThe 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.
True TrailsQuantum 2 features Raymarine’s new True Trails target history display. The True Trails feature 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.
