Raymarine's HD Color technology brings radar users the power of digital signal processing with a truly adaptive transmitter and receiver that automatically adjusts to changing environmental and sea conditions.
Raymarine's HD Color scanners provide superior all weather performance allowing you to still see targets through rain and thunderstorms. Use radar to track weather too.
During this abnormally heavy rain storm (see left hand image), rain mode was used to cut the clutter to clearly reveal the targets (see right hand image).
Cut the clutter
Detect targets at very close proximity to your vessel, or at very long ranges to see distant vessels, land features and even weather fronts. Distinguish targets through even the heaviest rain clutter.
Use the radar to see the weather coming, then use the radar overlay to map the weather pattern onto the chart.
Track Targets - Not everything transmits AIS!
Using MARPA* (mini-automatic radar plotting aid) allows you to identify vessel, speed, bearing, closest point of approach (CPA) and time to closest point of approach (TCPA), dangerous/proximity alarms, overlay AIS info for further target clarification.
*For the best radar overlay and MARPA performance fit a smart heading sensor or an SPX autopilot course computer.
Important radar information
Powerful enough to slice through atmospheric clutter, Raymarine radars still comfortably meet international limits for energy absorption - in fact, the energy absorbed from an ordinary mobile phone can be several times greater than that from a correctly installed Raymarine radar.
All radars work on line-of-sight principles so although antennas could theoretically be fitted almost anywhere, unobstructed and parallel to the water line is better.
Raymarine's radars use interference rejection technology to resist signal interference from other vessels' transmissions as well as close proximity objects already fitted to the boat.
Pulsed magnetron vs broadband (FMCW) radar technology
Broadband (FMC) radars typically emit low levels of energy, resulting in loss of ultimate performance in conditions of fog, rain, spray and snow, and limiting target detection at longer ranges.
Raymarine pulsed magnetron radars combine low average energy with high peak powers allowing the radar to detect targets at greater ranges, and to punch through adverse weather conditions ensuring targets are identified.
RACON and SART
Raymarine radar antennas also trigger RACON beacons and home in on signals from Search And Rescue Transponders.
Raymarine has 3 different types of radar antenna
- Digital - 8 colour resolution
