Everything You Need to Know About Marine Radars

The marine radar of a ship is useful for providing the captain and crew awareness of other ships and land obstacles that are surrounding them during their voyage. Detection is achieved through the radar emission of a radio signal which bounces back to the radar when it comes into contact with another marine vessel or object, thus providing an estimate of surrounding targets. With this reading, the captain and crew can then enact collision avoidance and properly navigate the ocean safely.

There are many features that should be considered when choosing the right marine radar for your application, but two of the most important are the transmitter power and beam angle capabilities. Transmitter power is calculated by Kilowatts, and the more powerful the transmission, the more ability the radar antenna is going to have to detect objects during bad weather. Rain and fog can cause the radar to not read surrounding objects as well, decreasing your ability for navigation and collision avoidance. Beam angle of the radar antenna also plays a role in detection quality, as longer antennas create readings that allow for easier discerning between objects that are closer together. Shorter antennas, on the other hand, provide for scanning of a larger area. Both antenna types are useful and provide their advantages for the varying needs of vessels.

When traversing the sea, being aware of any surrounding marine vessel is crucial for the safety of everyone. Many larger ships may not be searching for smaller boats that are surrounding them, and this could cause very dangerous situations. As radars can have the capability of scanning upwards of 50 nautical miles surrounding the vessel, it can be very easy to detect other ships and change course as necessary to maintain safety. With the ability to track the course and speed of other boats, you can also be better prepared to accommodate when weather conditions change, as it can change rapidly at any time.

Marine electronics parts, such as GPS units, are also a great addition alongside your radar system. With a GPS, vessels can increase their safety and navigation abilities and units allow for chartplotting, route planning, and navigation. GPS may also provide for the emission of emergency broadcasts that will send your vessel’s coordinates out so that rescuers can easily locate you and provide assistance. Lastly, GPS can also help you remain on your intended course by providing warnings when you begin to stray off of the set path.

Altogether, marine electronics parts such as radars and GPS units allow for increased safety of traversing the sea. With a radar, captains and crew can be aware of surrounding objects, regardless of visibility, weather, or time of the day. GPS builds off of this ability, providing for improved navigation and emergency broadcasts for safety. There are many options for radar and antennas, and each provide their own advantages and disadvantages. Before choosing, it is helpful to consider the type of vessel you own, your intended use, and your needs for safely and efficiently travelling.
