AIR SURVEILLANCE RADAR SYSTEMS
Function. Air surveillance radar facility buildings provide housing
for electronic radar equipment used to detect and display location information
about in-flight aircraft. These facilities are unattended.
Radar Systems. This section describes the facilities which support
the radar systems discussed in pars. 4.2.1 and 4.2.2.
Airport Surveillance Radar (ASR). The ASR is an electronic radar
system used to obtain the range and azimuth of an aircraft. When equipped
with an ATCRBS, the ASR obtains altitude and identification of the aircraft.
Information obtained by the ASR and ATCRBS is displayed in the MTRACON, the
air traffic control tower with ground controlled approach or a joint control
facility (JCF). The ASR is used to control aircraft on overflight, approach,
and departure flight paths at a terminal facility. See Facility Plate 133-75
(Sheets 1 through 3 of 3).
Air Route Surveillance Radar (ARSR). The ARSR is an electronic
radar system used to obtain the range and azimuth of an aircraft. When
equipped with an ATCRBS, the ARSR obtains altitude and identification of the
aircraft. Information is displayed in the FACSFAC or JCF. The ARSR is used
to control airspace and enroute aircraft beyond the limits of an ASR. See
Facility Plate 133-76 (Sheets 1 through 3 of 3).
Location. Locate the ASR and ARSR building adjacent to the radar
facility antenna tower. Locate the ASR facility no less than one-half mile
from the closest runway to be served. The ASR facility at Range Airspace
Surveillance Sites (RASS) may be located further away. Locate the facility to
minimize obstruction to radar transmissions. Refer to NAVELEX 0101,107; FAA
Order 6310.6, Primary/Secondary Terminal Radar Siting Handbook; and FAA Order
6340.15, Primary/Secondary En Route Radar Siting Handbook.

Adequate space for equipment and equipment maintenance.
Clear ceiling height of 10 feet.
Restroom (refer to par. 2.4.8).
Structure. Design roof structural system to support cable trays and
Provide vinyl tile flooring in equipment room.
