Different Types of Radars Used in Ships.

The term RADAR stands for; Radio Detection and Ranging. It is a kind of detection system that employs radio waves to decide the angle, velocity, or range of objects. Radar can be used to detect whether formations, aircraft, motor vehicles, aircraft, spacecraft, terrain, guided missiles, and ships, among other many uses.

How Does Radar Work?

A radar system is made of a transmitter that produces electromagnetic waves in the radio or microwave domain. Radar uses the same antenna for receiving and transmitting the information. This tech works in that; the radio waves originating from the transmitter reflect off the target and back to the receiver relying on the information concerning the location of the object as well as its speed. This technique is widely used in ships.

Ships use both X-band as well as S-band frequency radar system, which plays the role of navigating and detecting approaching objects. Such can be other ships or any other obstacles which the ship might encounter while on the move. Detecting such objects is crucial to the ships as it helps prevent accidents that might occur from a collision. The radars employ antennas, which are usually rotating to get precise information about the ship’s surrounding area. This antenna is capable of detecting the targeted objects or points as well as displaying the obtained information on the screen.

Here are the types of radars used in ships:

  • Naval and Coastguard Radar.

This kind of radars is known to search the ship’s surrounding area and offer 3D surveillance. This radar is capable of detecting small targets in the distance during severe weather. This radar applies both S and X
band frequency mechanisms, making them able to detect minute objects from a distance.

  • 3D Radar.

This radar is capable of measuring the correct location of the targeted object in two dimensions. It is also able to provide the angle of elevation on the targeted object. It contains an antenna that is rotated either manually or automatically to give the target range.

  • Naval Fire-Control radar.

This radar’s critical role is to relay information to the navy officers on how they should project their arms to hit the target. This radar employs the use of radio waves to get an accurate track of the target as well as providing the object’s exact location.

  • Simple Pulse Radar.

This is the kind of radar that is common in the shipping industry. It is made of repetitive short-duration of pulses, which enable it to monitor any mobile object. It applies Doppler frequency to get the accurate distance of the object, which is moving.

  • VTS and Coaster Surveillance Radars.

This radar offers vessel traffic management services as well as water vessels like ships with a timely warning of approaching the target. They are the radars that provide security and safety within the coastlines, ports as well as waterways.

  • Small watercraft Radar.

These radars are commonly used on small boats. They are designed by use of sharpEyeTM SCV. This kind of design enables small crafts to detect targets within a range of 24NM.


Radar tech is a crucial component in every ship as it ensures that the ship is safe across the sea as well as when close to the shore. This technology is widely relied on since many industries, as well as many spheres of life, depend much on shipping. Embracing this technique is important as many people depend much on sea transport.
