Aero-Radionav. This band is used heavily for
radiolocation and radionavigation performing long-range air surveillance and enroute air-traffic control
functions. The DOD and FAA recently deployed a
modernized Air-Route Surveillance Radar Model 4
(ARSR-4) in this band for air-defense, drug
interdiction and air-traffic control.
FAA Aero-Radionav. The FAA and aviation users
depend upon air-route surveillance radars (ARSRs) to
obtain aircraft position information in support of
enroute air-traffic control.
Military Aero-Radionav. The Air Force and Navy
make use of it for high-power long-range surveillance
radars and air-traffic control radars, in support of
national defense missions.
Drug Interdiction. In this application, radar
equipment is mounted on tethered balloons along the
southern border of the U.S. to detect low-flying aircraft
entering U.S. airspace.
Radio Astronomy. Observations are made of highly
