How Does Marine Radar Work

Range and bearing are obtained by the fact that each component does a specific job at the correct time.

How does marine radar work. The radar system sends out a signal in the form of a sound wave. From compact and lightwight digital radomes to ultra high performance super hd colour open arrays raymarine has the perfect marine radar solution for every boat. The ship s position could be fixed by the bearing and distance information of a fixed reliable target on the radar screen. Garmin s fantom dome and open array radar work with their gpsmap series displays.

It helps in detecting boats birds landmasses and weather systems even if the visibility is less than usual. A marine radar device acts as a major navigation aid for boaters. If you need help in answering this question see our west advisor called marine radar for the recreational boater. Simrad s halo radomes work with their nss and nso displays among others.

This pulse is sent out from the radar dish on top of your boat. That s why anglers who may use a radar to search for birds which indicate feeding fish below often choose units with beam widths as low as 1 2 degrees so they can detect those. Marine radar is an instrument of perfect synchronization. A wide beam width six degrees for example won t penetrate nearly as far or pick up nearly as much as a tight two degree beam.

The second question concerns whether you want a radome or an open array. Once used only on large vessels radar units are now compact draw little electricity and are sized to fit boats as small as 18 in length. Radar systems let you see through darkness fog and stormy weather conditions. It can be used to detect aircraft ships spacecraft guided missiles motor vehicles weather formations and terrain a radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain a transmitting antenna a receiving antenna often the same.

Top features to consider. Marine radars are the best collision avoidance system ever developed for the recreational boater. The two fundamental features of a marine radar unit are transmitter power and beam angle. Radar beams work the same way.

But radar can also do six other things that no other electronic navigation device gps chart plotters and ais can do. Radar is a detection system that uses radio waves to determine the range angle or velocity of objects. Radar controls marine radar has performance adjustment controls for brightness and contrast also manual or automatic. Day and night systems from raymarine keep you aware of surrounding traffic hazards rain sea birds and much more.

It contains no calculator or computer to do its basic function. By steve smith. I m all about using radar for warning us about collision avoidance which is the first thing that radar does better than other marine electronics. Marine radar systems can provide very useful radar navigation information for navigators onboard ships.
