Raymarine Radar Antenna

Beam Sharpening Technology

Also called Antenna Boost, is digital technology that allows a small radar scanner to perform with characteristics like an antenna of a much larger physical size. Using patented Digital Signal Processing techniques, Raymarine’s Magnum Open Array radars use beam sharpening to provide map-like coastal detail, enhanced target separation, and increased sensitivity to weak and long-range targets.

MARPA Target Tracking

A collision avoidance feature allows your radar to acquire and track targets of interest. Targets can be acquired manually or automatically (on some systems.) After acquiring the target, the radar will calculate the target’s course, speed, closest point of approach (CPA) and time to CPA. On-screen symbology shows you the target’s direction and speed. Visible and audible cues warn you of developing dangerous situations.

High Speed Scanning

Allows select radar scanners to spin faster when operating at ranges below 3 miles. When high speed mode is enabled, and the selected range scale is 3 miles or less, the scanner will increase its rotation speed from 24 to 48 RPM. This effectively doubles the update rate of the scanner, allowing for better visibility and tracking of fast moving targets close to the boat.

Stabilized PPI Display

Allows the radar Plan Position Indicator (PPI) or scope to update in real-time even as the heading of the boat is changing. This gives you a smooth, accurate plot of all radar contacts when changing course or maneuvering, without having to wait for the radar scanner to sweep through a full rotation. Stabilized PPI requires the presence of a heading sensor like the Raymarine EV1or an Evolution Autopilot System.

AutoGST™ Technology

Refers to Raymarine’s adaptive transmitter and receiver. It automatically adjusts the Gain, Sea Clutter and Tuning for true hands-off operation. Auto GST continuously monitors the environment and adjusts these setting automatically for the best picture under all conditions.

Advanced Target Separation

ATX™ technology gives Quantum radars unsurpassed range resolution. Densely packed targets can be seen individually, rather than merged together as one large target.

Radar Overlay on Chart

Lets you see the live radar image as a semi-transparent layer on your navigation chart. This allows you to confirm the positions of navigation aids, other vessels, obstacles and landmass by comparing them to charted objects. Radar overlay is also very useful to boaters new to radar and looking to get comfortable interpreting the radar returns.

Timed Transmit Mode

A valuable power-saving feature for sailboats and electric boats. When enabled your radar scanner will automatically transmit at a selectable interval, and then go back into a low power standby mode. The reduces the overall duty-cycle of the radar while allowing you to maintain a long-range watch. The result is a significant savings of crucial battery power while underway

Radome or Open Array - What's the difference?

Marine radar systems fall into two primary categories: Open-Array or Enclosed Radome Systems.

 

Open Array Open-Array radar scanners are made of 2 parts. The radar pedestal houses the scanner’s electronics and drive mechanism. Atop the pedestal is mounted a radar antenna or array. Raymarine’s Magnum Open Array radar scanners consist of pedestals with 4kW or 12kW power output, and your choice of a 4-foot or 6-foot antenna array. Open-Array radars are easily identified by their rotating antennas. When choosing an open-array system you will need to consider the amount of space available on your boat, as well as the weight capacity of the location where you’ll be installing the radar scanner. Be sure to leave a clear radius around the pedestal to allow of the rotation of the antenna. Magnum open-array systems weigh approximately 60 pounds (27 kg) so make sure your radar arch, hard top, or other overhead structure is rated to carry that amount of weight. Open-array radars are generally more powerful and offer longer range capabilities than radome scanners. Open arrays offer enhanced details of shoreline and targets packed tightly together thanks to their larger antenna size. Radar systems use the length of their antenna array to focus the radar beam. Larger antennas make for more tightly focused beams. Open array scanners are also more sensitive to weak targets and targets at long range, again because of their larger antenna array.

Enclosed Radomes Scanners (Radomes) Enclosed Radome Scanners contain many of the same components as their open-array cousins, but all the moving pieces are housed inside an enclosure called a radome. This arrangement is especially popular on sailing vessels and small boats where there is a chance of sails, rigging, lines, or fishing tackle getting wrapped in a spinning antenna. Radome scanners are also much lighter weight than open-array scanners. Raymarine’s Quantum radar scanners are among the lightest available on the market weighing in at just over 12 pounds (5.6 kg.) Raymarine offers 2 series of radome radar scanners. Quantum radar systems are solid-state CHIRP radar systems with excellent performance at both short and long ranges, up to 24 miles. HD Color radome systems are excellent performers for small, high-performance coastal cruising and fishing boats. HD Color radars offer a powerful 4kW transmitter with 48-mile range, dual-range
