Tactical, Air Traffic Control and airfield radars

Type 82 "Orange Yeoman" radar

The radar head consists of a tower about 40ft high which houses the aerial turning gear, transmitter assembly, head receivers and secondary radar interrogation equipment; the whole is surmounted by an aerial array. To avoid the use of wave-guide slip rings, the transmitter assembly is rotated with the aerial array.

Radar Type 82 is a high performance volumetric search radar operating in S-band, producing a plan position picture of air activity out to a range of 150 miles and to a height in excess of 60,000ft. Elevation coverage is provided by a stacked-beam receiver system; this system has a height- finding capability and the video content of the beams can be displayed separately or in combination. A fan-beam receiver is installed; this is intended for use in adverse weather conditions and has no height finding capability.

The ATCC is a two-storied building approx ll5ft long by 90ft wide. Housed on the ground floor is a radar office and directly above it, on the first floor, is an operations room; adjacent to both and contained within the same building are administrative offices, rest rooms and toilet blocks

In the radar office is housed all waveform generating and data handling equipment, together with receiving and secondary radar decoding installations, and includes technical control and monitoring facilities. Also in the radar office are data link (microwave and land line) receiver terminals; these take in data from remote radar heads and enable the ATCRU control area to be extended to a range of 250 miles (but with no height finding capability).

The operations room has up to three tiers of radar consoles which are divided into a number of control teams. Each control team includes two Controller consoles, a Tracker console and a Height Operator console. Displays available at the radar consoles enable an aircraft's position and height to be determined in terms of Cartesian co-ordinates. This information, together with aircraft velocity, is held in data stores and is continually updated. By this means positional data on up to 64 aircraft (depending upon the installation) can be handled simultaneously. Additional display consoles are provided for supervisory staff (Watch Supervisor and Allocator).

Radar displays can be supplemented with displays of secondary radar video, video maps, and range and bearing markers or replaced by a synthetic display showing stored information. Expanded displays can be selected and aided-track facilities are available.

A tote board, situated at one end of the operations room and facing the radar consoles, displays information relating to aircraft under surveillance.
