B-vhf – a Multi-carrier Broadband Communications Concept for Air Traffic Management in the Vhf Band
In this paper we describe an European initiative aiming to establish a broadband Very High Frequency (VHF) aeronautical communications system based on a multi-carrier technology and demonstrate its benefits to the aeronautical community, together with its technological fundamentals. The European research project B-VHF (“Broadband VHF Aeronautical Communications System based on Multi-Carrier Tec...
متن کاملBroadband unidirectional behavior of electromagnetic waves based on transformation optics
High directive antennas are fundamental elements for microwave communication and information processing. Here, inspired by the method of transformation optics, we propose and demonstrate a transformation medium to control the transmission path of a point source, resulting in the unidirectional behavior of electromagnetic waves (directional emitter) without any reflectors. The network of inducto...
متن کاملVHF Profiler Observations of Winds and Waves in the Troposphere During DAWEX
A VHF atmospheric radar (wind profiler) was used to study tropospheric winds during DAWEX. The profiler, which operated at a frequency of 54.1 MHz, was located at Pirlangimpi (Garden Point) (11.4S, 130.5E) on the Tiwi Islands. Observations were made regularly up to heights near 8 km, with maximum heights occurring when convective activity was strongest. Mean winds observed between October and D...

متن کاملThe Coupling of Gravity Waves and Turbulence at White Sands, New Mexico, from VHF Radar Observations
Doppler spectra taken with the VHF Doppler radar at White Sands Missile Range are used to describe the winds and turbulence for 10 days in March-April 1991. The large power aperture product of this radar provides excellent data coverage in 150-m layers over the entire height range used, about 5-20 km. The results show that gravity-wave activity and small-scale turbulence are significantly enhan...
