Unreferenced date December 2009 A highfrequency approximation or high energy approximation for scattering or other wave propagation problems, in physics or engineering , is an approximation whose accuracy increases with the size of features on the scatterer or medium relative to the wavelength of the scattered particles. Classical mechanics and geometric optics are the most common and extreme highfrequency approximation, where the wave or field properties of, respectively, quantum mechanics and electromagnetism are neglected entirely. Less extreme approximations include, the WKB approximation , physical optics , the geometric theory of diffraction , the uniform theory of diffraction , and the physical theory of diffraction . When these are used to approximate quantum mechanics , they are called semiclassical approximations.

MWband freq 3 to 30 gigahertz GHz bands Super highfrequency or SHF refers to radio frequency radio frequencies RF in the range of 3 Hertz GHz and 30 GHz. Also known as the centimeter band or centimeter wave as the wavelengths range from ten to one centimeter s. Description The International Telecommunication Union ITU , an international civil organization established to standardized worldwide telecommunication s, have stated that the superhigh frequency is encountered between 100 mm to 10 mm. Super highfrequency electromagnetic waves are relatively short for radio waves . This frequency is used for microwave devices, Wireless LAN WLAN , most modern radar s.

The HighFrequency Content measure is a simple measure, taken across a signal spectrum usually a STFT spectrum , which can be used to characterize the amount of highfrequency content in the signal. The magnitudes of the spectral bins are added together, but multiplying each magnitude by the bin position proportional to the frequency . Thus if X k is a discrete spectrum with N unique points, its HighFrequency Content measure is math HFC sum i 0 N 1 i X i math In contrast to perceptual measures, this is not based on any evidence about its relevance to human hearing . Despite that, it can be useful for some applications, such as onset detection . The measure has close similarities to the spectral centroid measure, being essentially the same calculation but without normalization according to overall magnitude. References P. Brossier, J. P.

orphan date October 2009 Wikify date October 2009 HighFrequency Data Link HighFrequency Data Link HFDL is an ACARS communications media used to exchange data such as Aeronautical Operational Control AOC messages, Controller Pilot Data Link Communication CPDLC messages and Automatic Dependent Surveillance ADS messages between aircraft end systems and corresponding ground based HFDL ground stations. Using the unique propagation characteristics of highfrequency radio waves, the ground stations provide data link communications to properly equipped aircraft operating anywhere in the world. The result, pilots can always communicate with someone on the ground. Avionics Supporting HFDL To use the service, an aircraft only needs a Communications Management Unit CMU , or equivalent and an HFDL data radio. The CMU is an airborne communications router that interfaces with many aircraft communications systems including SATCOM, VHF, HFDL, FMS and others. Global Coverage Today, HFDL is an air ground data link standard with coverage in virtually every corner of the globe, approximately 168 million square miles where aircraft are never out of touch both in the air and on the ground. Evolving Technology The HFDL network and avionics are a continuing evolution. Recent innovations in avionics software developed by both Honeywell and Collins have enhanced performance and contribute to the service s outstanding message success rates. There is continued investment in the HFDL infrastructure and there is a long term strategy in place to ensure its success. ARINC have been quoted as saying that the system and its use have grown at rates above 20 for each of the past ten years and it now supports over sixty airlines with well over 1,200 aircraft sending more than 1 million messages a month. In 2009 ...

Unreferenced date December 2009 Orphan date February 2009 The HighFrequency Global Communications System HF GCS is a network of single sideband shortwave transmitters of the United States Air Force which is used to communicate with aircraft in flight, ground stations and some United States Navy surface assets. All worldwide receiving and transmitting sites in the HF GCS system are remotely controlled from Andrews AFB . Before 1 October 2002 it was known as the Global HighFrequency System GHFS . HF GCS stations tend to operate in the aviation bands clustered around 5, 8 and 11 12 MHz, although other frequencies are in use. The primary HF GCS voice frequencies are 4724.0 kHz, 6739.0 kHz, 8992.0 kHz, 11175.0 kHz, 13200.0 kHz and 15016.0 kHz. In addition to the HF GCS, U.S. aircraft frequently use Military Affiliate Radio System MARS HF stations 13927.0 kHz and Canadian Forces HF stations 11232.0 kHz to relay messages. One common use for the HF GCS is to place telephone calls from the aircraft in flight by means of the Defense Switched Network DSN to an Air Force base to obtain local weather conditions, to arrange for refueling, and to inform the base of the number of passengers and crew. The HF GCS also carries Emergency Action Messages . Although transmissions are often single sideband, the use of the Automatic link establishment ALE transmission mode is more and more common.
