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.
Marpa may refer to: Marpa Lotsawa (1012–1097), Tibetan Buddhist teacher credited with the transmission of many Buddhist teachings to Tibet from India; Marpa, Peru, ruins of a pre-Columbian town located along the Cotahuasi Canyon in the Andes range of southern Peru; MARPA, Modification and Replacement Parts Association; Mini-automatic radar ...
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.
Georgia, officially the State of Georgia, is a state in the Southeastern region of the United States. It borders Tennessee and North Carolina to the north, South Carolina and the Atlantic Ocean to the east, Florida to the south, and Alabama to the west.

The radar mile is the time it takes for a radar pulse to travel one nautical mile, reflect off a target, and return to the radar antenna. Since a nautical mile is defined as 1,852 m, then dividing this distance by the speed of light (299,792,458 m/s), and then multiplying the result by 2 yields a result of 12.36 μs in duration.
