Once accessible only to wealthier surfers, marine radar has enjoyed increased popularity due to lower prices, better designs, and the ability relative recent interface with navigation instruments such as GPS chartplotters and autopilots. Anyone who found themselves trying to navigate through dense fog or choose the navigation lights in the messy context of earth lights can appreciate the additional safety factor that brings marine radar coastal shipping and the sea. Whether interfaced with navigation instruments or not, is a powerful radar navigation device that can be used in any situation.
How Radar works
Radar systems are composed of a display and a rotating antenna (or scanner). A short current pulse of radio waves transmitted through the antenna and a computer inside the radar receiver measures the time delay of the received echo and calculates the distance to an object or land mass while rotating scanner determines the bearing. The results are shown on the radar screen.
Navigating with Radar
Boaters equipped with radar can more confidently extend their cruising grounds without feeling completely at the mercy of the dark or the sudden approach of showers. Radar allows boaters to see the land masses, other vessels or navigation aids that can usually hidden from view by the darkness or weather conditions. While rain and other precipitation significantly shorten the radius of action is effective, this sensitivity to precipitation also tends to make a radar detector useful to address the bad weather.
Most users operate the radar in the presentation on / To the front because it's so easy to interpret at a glance. This means that the top of the screen is always oriented with the bow of the boat, and objectives of the screen are always on the departure of the vessel.

Another display mode, True Presentation / North Up is designed as a letter with the boat in the middle and the top of the screen pointing north. This makes it possible to observe how they move on-screen navigation aids as the ship still in its planned route. Radars with a North-up mode are usually connected with an electronic compass.

The last and most versatile is the option Course Up so that you receive navigation information from GPS or Loran and / or an autopilot (optional). In this mode the top of the screen is related online course with the course of a selected POI. If the starting line of the drift boat off the rhumb line from any pilot error or current the resulting motion will show XTE (cross track error), which can be easily corrected. This is also the ideal way to avoid collisions.

Advice Selection
Display Type
The radars are now available with monochrome CRT, LCD monochrome or color TFT screen. The readability in all conditions Light is the key factor in determining the best display of a particular boat. Boat size and location of radar will greatly influence whether you choose one lightweight LCD screen or larger, heavier, high-resolution CRT screen. LCDs are most common in the cabs and on fly because they show well in the light of sun, are easily disconnected and stored below and some are waterproof. Monochrome CRT displays a better definition of direct sunlight, but are best installed permanently below or in a locked cupboard in the flybridge. However, with incredible visibility and lower prices, the most recent shows are now color TFT dominate the market.
Transmit Power
Small marine radar transmitting between 2-6 kW of energy, the transmission power to determine the force the signal from the antenna and the corresponding return echo – the stronger the transmitter, soft or distant targets are likely to show on screen. The transmission power is more important in bad weather as fog, rain and rain tend to absorb energy and reduce the radar. Antenna height is Radar also a factor because it is a line of vision system.
Open or closed array antenna?
As a rule, the larger the antenna, the better of its ability to distinguish objects that are near and in congested areas. Open arrays are generally larger and are found in powerboats. Closed sets, called domes, are usually reserved for sailboats, where protection of the sails and rigging is a concern.
Where to buy
To determine the best option for your boat's marine radar is often a good idea to speak with a specialist knowledge of marine electronics such as American MarineTech North. They can explain the features and capabilities of a special type of marine radar and offer suggestions based on the navigation style and budget. MarineTechNA offers a wide selection of marine radar and accessories. They also have a wide variety of other marine electronics manufacturers, such as GPS plotter, autopilot, locators, and more
