Ever wondered how the radar views every second & minutes if a Go Pro was fitted on the Scanner?
Watch this video & count the revolutions Scanner makes in a minute.
What is Marine Radar?
A mandatory aid to navigation, the radar is used in identifying, tracking (with integrated ARPA) and positioning of vessels (including one’s own vessel) among other things in order to adhere to the COLREGs so as to safely navigate a ship from one point to another.
The marine radar is classified under the x-band (10 GHz) or S-band (3GHz) frequencies. The x-band, being of higher frequency is used for a sharper image and better resolution whereas the S-band is used especially when in rain or fog as well as for identification and tracking.
With the help of ship radar, accidents can be prevented at sea with the use of the various inherent functionalities of the radar (determining the CPA and the TCPA, EBL, VRM etc).
However, even while the ships are docked in the port, with the help of these radars, the coast guard, VTS and the other authorities can use them to monitor the traffic in the small radar range.
How Does Marine Radar Works
The term “Radar” is an acronym for Radio Detection and Ranging”. The marine radar works on the basic principle of electromagnetic waves. The radar antenna sends the high-speed electromagnetic waves to establish the location, which is the distance, the velocity and the direction the wave travelled along with the altitude of the object, moving or stationary.
Electromagnetic energy travels through air at a high constant speed, equivalent to the speed of light (300,000 kilometres per second).
