Radar;
c. Displays or monitors used for air traffic control (ATC);
d. Meteorological (weather) radar;
e. Precision approach radar (PAR) equipment conforming to ICAO standards and employing electronically steerable linear (1‑dimensional) arrays or mechanically positioned passive antennae.
6. A. 008. a. Operating at frequencies from 40 GHz to 230 GHz and having any of the following:
1. An average output power exceeding 100 mW; or
2. Locating "accuracy" of 1 m or less (better) in range and 0.2 degree or less (better) in azimuth;
6. A. 008. b. A tunable bandwidth exceeding ± 6.25% of the 'centre operating frequency';
Technical Note:
For the purposes of 6A008.b., the 'centre operating frequency' equals one half of the sum of the highest plus the lowest specified operating frequencies.
6. A. 008. c. Capable of operating simultaneously on more than two carrier frequencies;
6. A. 008. d. Capable of operating in synthetic aperture (SAR), inverse synthetic aperture (ISAR) radar mode, or sidelooking airborne (SLAR) radar mode;
6. A. 008. e. Incorporating electronically scanned array antennae;
Technical Note:
For the purposes of 6A008.e., electronically scanned array antennae are also known as electronically steerable array antennae.
6. A. 008. f. Capable of heightfinding non‑cooperative targets;
6. A. 008. g. Specially designed for airborne (balloon or airframe mounted) operation and having Doppler "signal processing" for the detection of moving targets;
6. A. 008. h. Employing processing of radar signals and using any of the following:
1. "Radar spread spectrum" techniques; or
2. "Radar frequency agility" techniques;
6. A. 008. i. Providing ground‑based operation with a maximum 'instrumented range' exceeding 185 km;
Note: 6A008.i. does not apply to:
a. Fishing ground surveillance radar;
b. Ground radar equipment specially designed for enroute air traffic control and having all the following:
1. A maximum "instrumented range" of 500 km or less;
2. Configured so that radar target data can be transmitted only one way from the radar site to one or more civil ATC centres;
3. Contains no provisions for remote control of the radar scan rate from the enroute ATC centre; and
4. Permanently installed;
c. Weather balloon tracking radars.
Technical Note:
For the purposes of 6A008.i., 'instrumented range' is the specified unambiguous display range of a radar.
6. A. 008. j. Being "laser" radar or Light Detection and Ranging (LIDAR) equipment and having any of the following:
1. "Space‑qualified";
2. Employing coherent heterodyne or homodyne detection techniques and having an angular resolution of less (better) than 20 µrad (microradians); or
3. Designed for carrying out airborne bathymetric littoral surveys to International Hydrographic Organisation (IHO) Order 1a Standard (5th Edition February 2008) for Hydrographic Surveys or better, and using one or more "lasers" with a wavelength exceeding 400 nm
