Radar Circular Radar Targeting Radar targeting enables you to identify and track objects. About MARPA MARPA is primarily used for collision avoidance, through object targeting and tracking. To use MARPA, you must assign a MARPA tag to a target. The radar system automatically monitors the tagged object and provides you with information about the object, including the range, bearing, speed, GPS heading, nearest approach, and time to nearest approach. MARPA indicates the status of each tagged object (acquiring, lost, tracking, or dangerous), and the chartplotter can sound a collision alarm if the object enters your safe zone.

Concentric, dashed green rings radiate from the target while the radar is locking onto it. Target has been acquired. A solid green ring indicates the location of a target that the radar has locked onto. A dashed green line attached to the circle indicates the projected course over ground or the GPS heading of the target. Dangerous target is in range. A red ring flashes from the target while an alarm sounds and a message banner appears. After the alarm has been acknowledged, a solid red dot with a dashed red line attached to it indicates the location and the projected course over ground or the GPS heading of the target. If the safe-zone collision alarm has been set to Off, the target flashes, but the audible alarm does not sound and the alarm banner does not appear (page 18). Target has been lost. A solid green ring with an X through it indicates that the radar could not lock onto the target. Closest point of approach and time to closest point of approach to a dangerous target.
