Giraffe Agile Multi Beam is a digital antenna array radar. It provides multi-beam 3-Dimensional air coverage at 5.4 to 5.9 GHz. It has instrumented ranges of 30 km (19 mi), 60 km (37 mi) and 100 km (62 mi). The altitude coverage is extended from ground-level to 20,000 metres (66,000 ft) with 70-degree elevation coverage.
Digital antenna array. Digital antenna array (DAA) is a smart antenna with multi channels digital beamforming, usually by using fast Fourier transform (FFT). The development and practical realization of digital antenna arrays theory started in 1962 under the guidance of Vladimir Varyukhin ( USSR ).
This is a listing of Antenna TV's confirmed affiliates, arranged by U.S. state. There are links to and articles on each of the stations, describing their local programming, hosts and technical information, such as broadcast frequencies. In most markets, Antenna TV operates on a digital subchannel of the main station listed.
A television antenna, also called a television aerial (in British English ), is an antenna specifically designed for use with a television receiver (TV) to receive terrestrial over-the-air (OTA) broadcast television signals from a television station. Terrestrial television is broadcast on frequencies from about 47 to 250 MHz in the very high ...
The upper antenna is a Yagi design. UHF television broadcasting is the use of ultra high frequency (UHF) radio for over-the-air transmission of television signals. UHF frequencies are used for both analog and digital television broadcasts. UHF channels are typically given higher channel numbers, like the US arrangement with VHF channels ...
Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.
