Radars are rarely used alone in a marine setting. A modern trend is the integration of radar with other navigation displays on a single screen, as it becomes quite distracting to look at several different screens. Therefore, displays can often overlay an electronic GPS navigation chart of ship position, and a sonar display, on the radar display ...
This is an incomplete list of ground-based radars operated by the United States Marine Corps since the service first started utilizing radars in 1940. [1] The Marine Corps' has used ground-based radars for anti-aircraft artillery fire control, long range early warning, Ground-controlled interception (GCI), ground directed bombing, counter-battery radar, short-range cueing for man-portable air ...

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.
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.
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 ...
The Ground/Air Task Oriented Radar (G/ATOR) is a single material solution for the mobile Multi-Role Radar System and Ground Weapons Locating Radar (GWLR) requirements. It is a three-dimensional, short/medium-range multi-role radar designed to detect unmanned aerial systems, cruise missiles, air-breathing targets, rockets, artillery, and mortars.
The range of a surface-search radar is greatly increased compared to other roles due to several aspects of the sea surfaces and the objects in it. In low sea states , water makes an excellent reflector for radio signals, which helps maximize the signal strength as reflections off the water strike the targets in addition to the line-of-sight signal.
