16.1 Radar overviewRadar is used to provide information that can help you to tracktargets and measure distances and bearings.Radio Detection And Ranging (RADAR) is used at sea to detectthe presence of objects (known as ‘targets’) at a distance, and ifthey are moving, detect their speed.Radar works by transmitting radio pulses, then detectingreflections of these pulses (echoes) from objects in the area anddisplaying the reflections as targets on your display.Until you are familiar with interpreting the radar display, everyopportunity should be taken to compare the radar screenpatterns with visual targets, such as other boats, buoys andcoastal structures. You should practise harbor and coastalnavigation during daylight hours and in clear weather conditions.HD and SuperHD radarYour multifunction display can be used with radar scanners.HD and SuperHD radar scanners provide a range of advantages,making it easier to discern objects around your vessel.HD and SuperHD radar scanners provide:• Improved target detection.• Full-color image.• Dual Range operation.• SuperHD option. This effectively increases the transmitterpower by a factor of at least 2, and reduces the beamwidth bya similar amount.Note: You must connect a SuperHD radar scanner in orderto use the SuperHD option.Multiple radar scannersThe multifunction display only supports the use of 1 radar onthe network.When the radar application is opened, if multiple radar scannersare detected then a warning message shall be displayed.Additional scanners will need to be removed from the networkbefore the radar application will function.Radar FeaturesDepending on the type of Raymarine radar you have differentfeatures will be available to you, the table below shows whichfeatures and settings are supported by radar type:FeatureNon-HDDigitalRadome HDRadomeHD OpenArraySuperHDOpen ArrayColor Gain Auto /Manual(0-100%)Auto /Manual(0-100%)Auto /Manual(0-100%)FTC Off/On(0-100%)Sea Harbour /Coastal /Offshore/ Manual(0-100%)Auto /Manual(0-100%)Auto /Manual(0-100%)Auto /Manual(0-100%)Auto Mode:BuoyAuto Mode:HarborAuto Mode:OffshoreAuto Mode:CoastalAuto Mode:BirdFeatureNon-HDDigitalRadome HDRadomeHD OpenArraySuperHDOpen ArrayPowerBoostAntennaBoostInterferenceRejectionOff / Normal/ HighOff / On Off / On Off / OnTargetExpansionOff / Low /HighOff / On Off / On Off / OnMARPATargets10 25 25 25Dual RangeDual RangeRestrictionsN/AScannerSpeed24 RPM 24 RPM /Auto24 RPM /Auto24 RPM /AutoParkingOffset0-360degrees0-360degreesAntennaSize4ft / 6ft 4ft / 6ftDisplayTiming0-153.6m 0-767m(rangedependant)0-767m(rangedependant)0-767m(rangedependant)STC Preset 0-100%Gain Preset 0-100TuneCorrectionNote: Features not listed are supported by all types ofRaymarine Non-HD Digital, HD and SuperHD radars.160 New a Series / New c Series / New e Series
