SMART-L
SMART-L (Signaal Multibeam Acquisition Radar for Tracking, L band) is a long-range naval search radar introduced in 2002 by Thales Nederland, formerly Hollandse Signaalapparaten (Signaal). The digital antenna array has 24 elements; all are used for reception, while 16 are used for creating virtual receiver beams through digital beamforming. The beams' vertical elevation, and compensation for ship movement, is done electronically. Horizontal training is done by mechanically rotating the entire array. As designed, SMART-L has a maximum range of against patrol aircraft, and against stealthy missiles. A software upgrade, Extended Long Range (ELR) Mode, extends the maximum range for the detection of ballistic missiles to over 2000 km, since 2018 all 4 Zeven Provincien class Frigates of the Royal Netherlands Navy have been equipped with the update. On the 25th of September 2017, as part of the exercise Formidable Shield 2017 the SMART-L MM radar system mounted on the test tower ...

Thales Nederland
Thales Nederland B.V. (formerly Hollandse Signaalapparaten B.V. or in short Signaal) is a subsidiary of the French multinational company Thales Group based in the Netherlands. The firm was founded as ''NV Hazemeyer's Fabriek van Signaalapparaten'' during 1922 by Hazemeyer and Siemens & Halske to produce naval fire-control systems. During the Second World War, the company's factory was captured and pillaged by the German Army; shortly after the conflict's end, the remaining assets were nationalised by the Dutch government, the company being renamed ''N.V. Hollandsche Signaalapparaten'' (or ''Signaal'' for short). During 1956, the Netherlands-based electronics company Philips became the majority owner of Signaal after buying a large portion of the shares from the government. The firm expanded throughout much the Cold War period, producing various naval electronics and defense systems for a range of customers around the world. During 1990, the French electronics and defence contr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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). History The history of the DAA was started to emerge as a theory of multichannel analysis in the 1920s.Slyusar V. I. Origins of the Digital Antenna Array Theory.// International Conference on Antenna Theory and Techniques, 24–27 May 2017, Kyiv, Ukraine. – Pp. 199 - 20/ref> In the 1940s this theory evolved to the theory of three-channel antenna analyzers. The implementation of effective signal processing in radars by the end of the 1950s predetermined the use of electronic computers in this field. In 1957, Ben S. Meltont and Leslie F. Bailey published article regarding using algebraic operations for signal processing with the help of electronic circuits or analog computer. Three years after in 1960 th ...

F 220 Fregatte Hamburg
F, or f, is the sixth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ef'' (pronounced ), and the plural is ''efs''. History The origin of 'F' is the Semitic letter ''waw'' that represented a sound like or . Graphically it originally probably depicted either a hook or a club. It may have been based on a comparable Egyptian hieroglyph such as that which represented the word ''mace'' (transliterated as ḥ(dj)): T3 The Phoenician form of the letter was adopted into Greek as a vowel, ''upsilon'' (which resembled its descendant ' Y' but was also the ancestor of the Roman letters ' U', ' V', and ' W'); and, with another form, as a consonant, ''digamma'', which indicated the pronunciation , as in Phoenician. Latin 'F,' despite being pronounced differently, is ultimately descended from digamma and closely resembles it in form. After sound changes eliminated ...

D Band (NATO)
The NATO D band is the obsolete designation given to the radio frequencies from 1.0 to 2.0 GHz (equivalent to wavelengths between 30 and 15 cm) during the cold war period. Since 1992 frequency allocations, allotment and assignments are in line to NATO Joint Civil/Military Frequency Agreement (NJFA). However, in order to identify military radio spectrum requirements, e.g. for crises management planning, training, Electronic warfare Electronic warfare (EW) is any action involving the use of the electromagnetic spectrum (EM spectrum) or directed energy to control the spectrum, attack an enemy, or impede enemy assaults.

Thales Group
Thales Group () is a French multinational company that designs, develops and manufactures electrical systems as well as devices and equipment for the aerospace, defence, transportation and security sectors. The company is headquartered in Paris' business district, La Défense, and its stock is listed on the Euronext Paris. Having been known as Thomson-CSF since its foundation in 1968, the company was rebranded ''Thales'' (named after the Greek philosopher Thales and pronounced , reflecting its pronunciation in French) in December 2000. A communication audit, launched in spring that year, highlighted Thomson-CSF's image deficit, particularly among the young French graduates it was seeking to recruit. The wish to liven up its image as well as the expansion of its business worldwide were cited among the reasons for the change. Thales is partially owned by the French State and operates in more than 56 countries. It had 80,000 employees and generated €18.4 billion in revenues in ...

Sea Radars
The sea, connected as the world ocean or simply the ocean, is the body of salty water that covers approximately 71% of the Earth's surface. The word sea is also used to denote second-order sections of the sea, such as the Mediterranean Sea, as well as certain large, entirely landlocked, saltwater lakes, such as the Caspian Sea. The sea moderates Earth's climate and has important roles in the water, carbon, and nitrogen cycles. Humans harnessing and studying the sea have been recorded since ancient times, and evidenced well into prehistory, while its modern scientific study is called oceanography. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, amongst many other elements, some in minute concentrations. Salinity varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary li ...

Stealth Technology
Stealth technology, also termed low observable technology (LO technology), is a sub-discipline of military tactics and passive and active electronic countermeasures, which covers a range of methods used to make personnel, aircraft, ships, submarines, missiles, satellites, and ground vehicles less visible (ideally invisible) to radar, infrared, sonar and other detection methods. It corresponds to military camouflage for these parts of the electromagnetic spectrum (i.e., multi-spectral camouflage). Development of modern stealth technologies in the United States began in 1958, where earlier attempts to prevent radar tracking of its U-2 spy planes during the Cold War by the Soviet Union had been unsuccessful. Designers turned to developing a specific shape for planes that tended to reduce detection by redirecting electromagnetic radiation waves from radars. Radiation-absorbent material was also tested and made to reduce or block radar signals that reflect off the surfaces of air ...
