Quantum 2 Q24D Radar Doppler with 15M Power & Data CablesThe Raymarine Quantum 2 Radar has 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 TargetsRaymarine Quantum 2 Doppler target processing readily identifies and color codes moving radar contacts for instant recognition and reduced risk of collision.Safer NavigationQuantum 2s 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 AvoidanceDoppler-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.Features:Doppler moving target display allows for superior situational awareness at-a-glanceFully automatic ARPA target tracking, along with manual MARPA modeAdjustable TrueTrails target history shows the motion history of moving contactsCHIRP Pulse Compression detects contacts as close as 18-feet for zero-visibility navigation24-mile range for early detection of traffic, navigation aids, landfall and weatherImmediate awareness Quantum starts up and is ready to go in secondsSuperior interference rejection eliminates noise from other radarsSimplified installation with Wi-Fi or thin wire network connectivityEasy upgrade Quantum 2 fits the same bolt pattern as other Raymarine scannersLightweight and easy to install Quantum weighs up to 50% less than comparable magnetron radarsSafe emissions mount Quantum anywhere onboardLow power consumption for extended battery life under sailHow 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 targets 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.Doppler Target ProcessingDoppler 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 redOutbound targets are colored greenColor coded targets make it simple to pick out moving traffic from other stationary targets like land, navigation aids or stopped/anchored vessels.Quantum 2 Safety SectorDoppler 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:BuoysExposed Hazard (rocks, pilings, etc…)Slow moving, low visibility vesselsQuantum 2’s Safety Sector spreads 15 from the bow to a distance of approximately 200mNOTE: 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 automatic
