    en.wikipedia.org/wiki/Marine_radar

    Commercial marine radar display. Land areas are shown in yellow, and vessel tracks are displayed with green "tails" on the screen. Marine radar systems can provide very useful radar navigation information for navigators on board ships. The ship's position could be fixed by the bearing and distance information of a fixed, reliable target on the ...

    en.wikipedia.org/wiki/Automatic_radar_plotting_aid

    A typical shipboard ARPA/radar system. A marine radar with automatic radar plotting aid (ARPA) capability can create tracks using radar contacts. [1] [2] The system can calculate the tracked object's course, speed and closest point of approach [3] (CPA), thereby knowing if there is a danger of collision with the other ship or landmass.

    The detection range between these devices and ships, dependent upon the height of the ship's radar mast and the height of the Search and Rescue Locating device, is normally about 15 km (8 nautical miles). Once detected by radar, the Search and Rescue Locating device will produce a visual and aural indication to the persons in distress.

  5. Mini-automatic radar plotting aid - Wikipedia

    en.wikipedia.org/wiki/Mini-automatic_radar...

    Mini-automatic radar plotting aid (or MARPA) is a maritime radar feature for target tracking and collision avoidance. Targets must be manually selected, but are then tracked automatically, including range, bearing, target speed, target direction (course), CPA (closest point of approach), and TCPA (time of closest point of approach), safe or dangerous indication, and proximity alarm.

    en.wikipedia.org/.../Air_Task_Oriented_Radar

    The AN/TPS-80 Ground/Air Task Oriented Radar (G/ATOR) is the United States Marine Corps next-generation Air Surveillance/Air Defense and Air Traffic Control (ATC) Radar. The mobile active electronically scanned array radar system is being developed by Northrop Grumman and was expected to reach initial operating capability in August 2016.

  7. List of radar types - Wikipedia

    en.wikipedia.org/wiki/List_of_radar_types

    Marine radars are used by ships for collision avoidance and navigation purposes. The frequency band of radar used on most ships is X band (9 GHz/3 cm), but S band (3 GHz/10 cm) radar is also installed on most oceangoing ships to provide better detection of ships in rough sea and heavy rain condition.

  9. Radar signal characteristics - Wikipedia

    en.wikipedia.org/wiki/Radar_signal_characteristics

    A civil marine radar, for instance, may have user-selectable maximum instrumented display ranges of 72, or 96 or rarely 120 nautical miles, in accordance with international law, but maximum unambiguous ranges of over 40,000 nautical miles and maximum detection ranges of perhaps 150 nautical miles. When such huge disparities are noted, it ...
