3.1 Product overview
The Quantum™ 2 Doppler Radome is a compact, solid-state Radar scanner,
utilizing MARPA technology for target tracking, CHIRP pulse compression for
improved range resolution, Doppler technology to make it easier to track
moving objects, and Wi-Fi connectivity for easier installation. In conjunction
with a compatible multifunction display, the Quantum™ 2 Doppler scanner
provides a map-like representation of the area around your vessel, enabling
you to identify other vessels, buoys, and land features such as coastlines
and hills.
The Quantum™ 2 Doppler Radome has the following features:
• Solid-state technology (no magnetron) for improved efficiency, and rapid
start-up.
• Range performance up to 24 nm (dependent on installation location).
• Doppler display, making it easier to track approaching and receding
objects.
• MARPA for target tracking (up to 25 targets) and collision avoidance.
• CHIRP pulse compression for improved target range resolution, and
reduced background noise.
• Wireless data connection via Wi-Fi, or wired connection via RayNet cable.
• Radar image display and control via Raymarine multifunction display.
• 24 RPM scanner rotation.
• Low power consumption.
• 12 V or 24 V operation.
Product and system overview
• Waterproof to IPx6.
Multiple Quantum Radar scanners
Only 1 (one) Quantum™ Radar scanner can be used at any one time, per
networked system.
If you have more than one Quantum™ Radar scanner installed on your vessel
and want to use them at the same time, the multifunction displays to which
the scanners are connected must NOT be networked together. This applies
to Quantum™ scanners connected either wired or wirelessly.

Doppler Radar overview
Doppler Radar technology makes it easier to track moving objects with
ground speed exceeding 3 knots.
The Doppler function highlights objects on the Radar display that are moving
towards or away from the vessel (e.g. other vessels, but not land or buoys,
for example). Stationary targets will not be highlighted.
Doppler Radar technology is particularly beneficial in a marine environment,
where poor weather conditions and visibility can make object tracking
challenging. With the integration of Doppler information on the Radar display,
the process of matching on-screen Radar returns with real-world objects
becomes a much simpler task.
Doppler Radar works by transmitting a microwave signal which is then
reflected off a moving object at a distance. By analyzing how the object's
motion has altered the frequency of the returned signal, the Doppler Radar
can interpret the variation to provide highly accurate measurements of an
object's direction of travel, relative to the Radar scanner.
