Things You Need To Know About Marine Radar

marine installation

Marine radars are the primary navigation device every boat needs. People often think that radar is only essential for shipping boats as it is useful in identifying, tracking. But the reality is every boat needs a marine radar irrespective of the purpose of your boat. Marine radars are classified under S-band (3 GHz) and x-band (10 GHz) frequencies. The latter is higher and used for better resolution and sharper images, while the former has the specialty to work in rain and fog. 

Noteworthy is that the marine installation in your boat must be compatible with other features, particularly in radar setup. You can install any size of radar in your boat. People often think that large-sized radars are better in terms of functionality and compatibility with your boat. But the reality is the boat having a radar of less size and a smaller structure will be a more efficient one.

Do you want to know how marine radars will work in your boat? Well! In this blog, you will get a brief knowledge about everything you need to know about Marine radars.

Why does every boat need a radar antenna?

Every boat must be equipped with a radar antenna because this device is important for your safety. Due to the reliable and durable collision avoidance technologies, you need a radar antenna. Just think about the night of the fog and stormy weather when there is less visibility. How will you keep your boat safe from collisions? Yes! Definitely, it would be best if you have something that can keep your boat safe. By using ship radars, not only will it keep your boar safe from accidents, but also you will be able to enjoy better control on your boat.

Important Features of Marine Radars

Here are some main features that you need to check on your radar.

  • The time and frequency of reflections observed by the radar receiver help determine location irrespective of the route. However, the pulse travels twice during hitting to target and back as observed by receiver and transmission. That’s why the target present on the PPI is basically half of its range.
  • When it comes to the PPI, these reflections are observed in such a way that it becomes even easier to identify the actual distance of targets and objects.
  • Furthermore, the electromagnetic waves are transmitted and received by parabolic radar antenna and often bounce back by hitting an object and then displayed on the screen.

In fact, the best radars having all these features to operate in the best way are Garmin Radars. So, you should install those radars in your boat to enjoy a luxury boating experience.

Working Process of a Radar in Boat

As radar is used to determine objects’ distance and position, you need to detect them by reflecting radio waves through the transmission. You know what the waves generally emitted from the radar antenna are known as pulses due to their electromagnetic nature. After the collision of these pulses with other boats and objects, they will be reflected and picked up through the radar antenna. By keeping the multi-functionality of radar ON, you can evaluate all the information over the display. Hence, these continuous rotations in all directions keep you safe.

Expected Faults and Errors in Radar

In order to keep your boating more secure and reliable, you must check your radars’ performance time by time. Do you wonder WHY? Well! The reason is the radar may have an error and fault during its operation. To observe and point out the faults and errors, you must be aware of those abnormalities.

Here are some common faults and errors that may occur on your radar.

1-  False Echoes

The main fault and abnormality that can occur in your radar is the production of false echoes. It usually happens when a number of boats simultaneously use radars within the same ranges. In such situations, glitches appear on these screens. If you face this error, you need to filter it out by using interference suppression settings.

2- Interference

Interference can also appear on your display screen in the form of spiral points when many vessels operate within the same range. These false interference echoes can also be filtered out and reduced by using the same interference suppression settings.

3- Reception Losses and Gaps

Whenever the time duration between transmission and reception of a wave is less, the radar antenna works at the minimum speed. However, gaps may occur during transmission and reception that cause losses, particularly when an object is picked up from long distances. Garmin radars are designed to switch to large ranges for transmission of impulses with minimum loss by keeping this functionality.

Uses of Marine Radar

In general, the best marine radars have a screen used to display all the objects and targets present within their range. As all the objects can be observed on the screen due to increased visibility, we suggest monitoring and navigating the boat position accordingly. In short, marine radars are navigation facilitators. The following are some uses of marine radars:

  •       Calculates ranges and distance-bearing targets.
  •       Uses range information in determining speed.
  •       It helps in integration with other shipping devices.
  •       Facilitates vessel navigation to avoid a collision.
  •       Beneficial in controlling the coastal traffic through VTS.
  •       Make use of the parallel index and other features for reliable navigation.
  •       It is often facilitated in the pilotage for navigation and traffic control.
  •       Useful in weather determination by predicting it up-to-mark.
  •       Helps in the differentiation of targets during high traffic places.

Final Words

Above all, the best marine radar has all the mentioned features and functionalities for better navigation. If you are looking for a perfect marine radar for your boat, we suggest you check Garmin Marine Radar from Marine Tech Miami. Feel free to upgrade your boat with these radar systems.
