It is capable of identifying aircraft using secondary radar up to a 200-nautical-mile (370 km) radius and primary radar coverage to 60 nautical miles (110 km). The PAR provides both azimuth and elevation information from 15-nautical-mile (28 km) to touchdown. Both the PAR and ASR can be used as final approach aids. The unit has three ASR ...
Exponentiation of both side leads to the formula for the equivalent radius. The formula for the equivalent radius provides consistent results. If the conductor cross-section dimensions are scaled by a factor , the equivalent radius is scaled by | |. Also, the equivalent radius of a cylindrical conductor is equal to the radius of the conductor.
For a traditional PAR, the ability to track the aircraft position is dependent on the aircraft radar cross section. TLS is based on transponder multilateration and trilateration and consequently tracks all aircraft that respond to the interrogations. Omnidirectional antenna surveillance coverage of the TLS extends to 100 nautical miles. [2]
The AN/FRD-10 is a United States Navy circularly disposed antenna array (CDAA), built at a number of locations during the Cold War for high frequency radio direction finding and signals intelligence. In the Joint Electronics Type Designation System , FRD stands for fixed ground, radio, direction finding. 14 sites were originally constructed as ...
Height above average terrain (HAAT), or (less popularly) effective height above average terrain (EHAAT), is the vertical position of an antenna site above the surrounding landscape. HAAT is used extensively in FM radio and television , as it is more important than effective radiated power (ERP) in determining the range of broadcasts ( VHF and ...
The antenna is a 22.0 ft × 4.6 ft (6.7 m × 1.4 m) elliptical reflector of open lattice construction, mounted on a small two-wheeled trailer. Rotation rate is 20 rpm, the BCC – Battery Control Central and the CWAR are synchronized by the PAR revolutions and the PAR system trigger. AN/MPQ-50 (Improved Hawk to Phase III)
