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]
Precision approach radar or PAR is a type of radar guidance system designed to provide lateral and vertical guidance to an aircraft pilot for landing, until the landing threshold is reached. [1] Controllers monitoring the PAR displays observe each aircraft 's position and issue instructions to the pilot that keep the aircraft on course and ...
The AN/TPS-75 is a transportable passive electronically scanned array air search 3D radar produced in the United States. It was originally designated the TPS-43E2. Although the antenna is a radically new design from the TPS-43, the radar van itself, which houses the transmitter, receiver processors, and displays is very similar to the older TPS ...
For directional antennas, the Yagi antenna is the most widely used as a high gain or "beam" antenna. For television reception, the Yagi is used, as well as the log-periodic antenna due to its wider bandwidth. Helical and turnstile antennas are used for satellite communication since they employ circular polarization.
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 ...
Q-par Angus was a designer and manufacturer of microwave and RF antennas for commercial and defense use; in May 2013 the company was acquired by Solid State PLC. [ 1 ] The company was formed in 1973 in Birmingham, UK, by Dr Richard Holliday and his wife Jenny Holliday.
Tail fin housing assembly for the AN/ALQ-99 equipment, seen during an EF-111A conversion. The AN/ALQ-99 has been used during the Vietnam War (1972–1973), Operation El Dorado Canyon (1986 American raid in Libya), 1991 Gulf War, Operation Northern Watch (1992–2003), Operation Southern Watch (1997–2003), 1999 Balkans War, 2003 Second Gulf War, and 2011 Operation Odyssey Dawn.
