Definition: RADAR
Radio Detection and Ranging
A radio detective device which provides information on range, azimuth and/or elevation of objects.
Definition: Primary Radar
A radar system which uses reflected radio signals.
Definition: Secondary Radar
A radar system wherein a radio signal transmitted from the radar station initiates the transmission of a radio signal from another station.
Definition: Surveillance Radar
Radar equipment used to determine the position of an aircraft in range and azimuth.
Definition: Primary Surveillance Radar (PSR)
A surveillance radar system which uses reflected radio signals.
Definition: Secondary Surveillance Radar (SSR)
A surveillance radar system which uses transmitters/receivers (interrogators) and transponders.
Definition: Situation Display
An electronic display depicting the position and movement of aircraft and other information as required.
Definition: Clutter
The visual indication on a situation display of unwanted signals.
Definition: Radar Position
The visual indication on a radar display of the position of an aircraft obtained by PSR and/or SSR.
Definition: Position Indication (PI)
The visual indication in non-symbolic and/or symbolic form, on a situation display, of the position of an aircraft, aerodrome vehicle or other object.
What can be "other objects"?
f.e. high antennas (can be equipped with a transponder)
Definition: Position Symbol (PS)
The visual indication, in symbolic form, on a situation display, of the position of an aircraft, aerodrome vehicle or other object obtained after automatic processing of positional data derived from any source.
Definition: PSR Blip
The visual indication, in non-symbolic form, on a radar display, of the position of an aircraft obtained by primary radar.
Definition: Identification
The situation which exists when the position indication of a particular aircraft is seen on a situation display and positively identified.
Definition: Radar Contact
The situation which exists when the radar position of a particular aircraft is seen and identified on a situation display.
