2. Radar definitions (and acronyms)
For the purposes of this document, the following terms and definitions apply. The Authoritative DictionaryofIEEE Standards Terms (B3] should be referenced for terms not defined in this clause.
acquisition: The process of establishing a stable track on a target that is detected by a radar during searchor designated in one or more coordinates from another source. When designated, a search of a limited givenvolume of coordinate space is usually required because of errors or incompleteness of the designation.
acquisition probability: The probability of establishing track on a designated target or a target detected insearch. See also: tracking.
active electronically scanned array (AESA) radar: A radar that uses an antenna with distributed transmitand receive elements co-located with the antenna, each of which may be individually controlled inamplitude, time delay, and/or phase providing very rapid electronic beamm scanning.
aided tracking: A tracking technique in which the manual correction of the tracking error corrects the rateof motion of the tracking mechanism.
Al radar: See: airborne-intercept radar.
airborne early warning (AEW) radar: Describing an early-warning or air-surveillance radar carried byan airborne or spaceborne vehicle. See also: early-warning radar.
NOTE–The abbreviations capitalized in this standard are in accordance with prevailing radar usage. Lowercaseabbreviations are an acceptable alternative (and are preferred by some authors and editors) provided they are used in aconsistent manner.~
airborne-intercept (Al) radar: A fire-control radar for use in interceptor aircraft
airborne moving-target indication (AMTI): See: airborne MTI
airborne moving-target indication (AMTI) radar: An MTI radar flown in an aircraft or other movingplatform with corrections applied for the effects of platform motion, which include the changing clutterDoppler frequency and the spread of the clutter Doppler spectrum See also: displaced phase centerantenna; space-time adaptive processing; time-averaged-clutter coherent airborne radar.
airport surface detection equipment (ASDE): A high-resolution radar usually located on the airportcontrol tower or other high point and used for observation of the positions of aircraft and other vehicles onthe surface of an airport.
airport-surveillance radar (ASR): A medium-range (e.g, 100 km) surveillance radar used to controlaircraft in the vicinity of an airport.
air-route-surveillance radar (ARSR): A long-range (e.g., 350 km) surveillance radar used to controlaircraft on airways beyond the coverage of airport-surveillance radar (ASR).
