Heading Line Adjustment:

the Heading Line is used to make sure

the green heading line (zero point) on your radar display is lined up the

bow of your vessel.

Heading Up

: when your heading is displayed at the top of the screen,

you are in Heading Up mode.

Interference Rejection

: filters out signals from other radars close to

your location.

North Up

: a stabilized display mode in which North is at the top of the

radar display. This display mode requires a heading sensor.

Offset EBL

: an electronic bearing line originating from a location other

than the PPI sweep origin.

Offset Mode:

moving the sweep origin (center of the PPI) to a location

other than the center of the radar display.

Open Array Antenna

: a radar antenna which has an external rotat-

ing scanner.

PPI (Plan Position Indicator)

: The PPI provides a map-like repre-

sentation of target echoes.

Radar Overlay

: radar image data laid over an electronic chart. This

feature requires a GPS position fix and a heading sensor. Radar Over-
lay is available only on GPS units and Sonar-GPS combo units.

Radome

: a single housing containing a radar antenna and transceiver.

Rain Clutter

: undesirable echoes caused by rain or snow.

Range

: distance to a particular target.

Range Rings

: fixed rings on the radar display designed to show the

distance from the antenna.

Sea Clutter

: undesirable returns caused by smaller waves and water

movement.

Standby

: radar mode that follows warm-up and precedes the start of

transmission.

Sweep Origin

: the origin of EBL and VRM, the sweep origin is located

at the center of the PPI.

Target

: an item detected by radar.

Target Acquisition

: process of locking on and starting to track a tar-

get with an ARPA radar.
