Signals Intelligence
Signals intelligence (SIGINT) is intelligence-gathering by interception of ''signals'', whether communications between people (communications intelligence—abbreviated to COMINT) or from electronic signals not directly used in communication (electronic intelligence—abbreviated to ELINT). Signals intelligence is a subset of intelligence collection management. As classified and sensitive information is usually encrypted, signals intelligence in turn involves the use of cryptanalysis to decipher the messages. Traffic analysis—the study of who is signaling whom and in what quantity—is also used to integrate information again. History Origins Electronic interceptions appeared as early as 1900, during the Boer War of 1899–1902. The British Royal Navy had installed wireless sets produced by Marconi on board their ships in the late 1890s, and the British Army used some limited wireless signalling. The Boers captured some wireless sets and used them to make vital transmis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Side Looking Airborne Radar
Side-looking airborne radar (SLAR) is an aircraft- or satellite-mounted imaging radar pointing perpendicular to the direction of flight (hence ''side-looking''). A squinted (nonperpendicular) mode is possible also. SLAR can be fitted with a standard antenna (real aperture radar) or an antenna using synthetic aperture. The platform of the radar moves in direction of the x-axis. The radar "looks" with the looking angle ''θ'' (or so called off-nadir angle). The angle ''α'' between x-axis and the line of sight (LOS) is called cone angle, the angle ''φ'' between the x-axis and the projection of the line of sight to the (x; y)-plane is called azimuth angle. Cone- and azimuth angle are related by cos''α'' = cos''φ'' ∙ cos''ε''. On the earth surface the wave comes in at the (nominal ellipsoidal) incident angle ''β'' with respect to the vertical axis at this point. (In some publications the incident angle is denominated to as ''θi''.) The antenna illuminate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-control Radar
A fire-control radar (FCR) is a radar that is designed specifically to provide information (mainly target azimuth, elevation, range and range rate) to a fire-control system in order to direct weapons such that they hit a target. They are sometimes known as targeting radars, or in the UK, gun-laying radars. If the radar is used to guide a missile, it is often known as a target illuminator or illuminator radar. A typical fire-control radar emits a narrow, intense beam of radio waves to ensure accurate tracking information and to minimize the chance of losing track of the target. This makes them less suitable for initial detection of the target, and FCRs are often partnered with a medium-range search radar to fill this role. In British terminology, these medium-range systems were known as tactical control radars. Most modern radars have a track-while-scan capability, enabling them to function simultaneously as both fire-control radar and search radar. This works either by having t ...

Ural-4320
The Ural-4320 is a general purpose off-road 6×6 vehicle, produced at the Ural Automotive Plant in Miass, Russia for use in the Russian army. Introduced in 1976, it is still in production today. The wheel arrangement for the Ural-4320 was designed for transporting cargo, people and trailers on all types of roads and terrain. It also serves as a launching platform for the BM-21 "Grad" rocket launcher. __TOC__ Gallery File:Ural-4320 with headlights in bumper.jpg, Ural-4320 with headlights in bumper (civilian version since mid-1990s) File:Ural-4320 with the headlights in the wings.jpg, Ural-4320 with headlights in wings (civilian and military versions before mid-1990s and current military version) Specifications Early versions of the Ural-4320 were fitted with the KamAZ-740 V8 diesel engine, ohv, displacement 10,857 cc (bore/stroke ratio ), compression ratio 16:1.

Business Insider
''Insider'', previously named ''Business Insider'' (''BI''), is an American financial and business news website founded in 2007. Since 2015, a majority stake in ''Business Insider''s parent company Insider Inc. has been owned by the German publishing house Axel Springer. It operates several international editions, including one in the United Kingdom. ''Insider'' publishes original reporting and aggregates material from other outlets. , it maintained a liberal policy on the use of anonymous sources. It has also published native advertising and granted sponsors editorial control of its content. The outlet has been nominated for several awards, but is criticized for using factually incorrect clickbait headlines to attract viewership. In 2015, Axel Springer SE acquired 88 percent of the stake in Insider Inc. for $343 million (€306 million), implying a total valuation of $442 million. In February 2021, the brand was renamed simply ''Insider''. History ''Busi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annexation Of Crimea By The Russian Federation
In February and March 2014, Russia invaded and subsequently annexed the Crimean Peninsula from Ukraine. This event took place in the aftermath of the Revolution of Dignity and is part of the wider Russo-Ukrainian War. The events in Kyiv that ousted Ukrainian president Viktor Yanukovych on 22 February 2014 sparked pro-Russian demonstrations as of 23 February against the (prospected) new Ukrainian government. At the same time Russian president Vladimir Putin discussed Ukrainian events with security service chiefs remarking that "we must start working on returning Crimea to Russia". On 27 February, Russian troops captured strategic sites across Crimea, followed by the installation of the pro-Russian Aksyonov government in Crimea, the Crimean status referendum and the declaration of Crimea's independence on 16 March 2014. Although Russia initially claimed their military was not involved in the events, Putin later admitted that troops were deployed to "stand behind Crimea's ...

Pravda
''Pravda'' ( rus, Правда, p=ˈpravdə, a=Ru-правда.ogg, "Truth") is a Russian broadsheet newspaper, and was the official newspaper of the Communist Party of the Soviet Union, when it was one of the most influential papers in the country with a newspaper circulation, circulation of 11 million. The newspaper began publication on 5 May 1912 in the Russian Empire, but was already extant abroad in January 1911. It emerged as a leading newspaper of the Soviet Union after the October Revolution. The newspaper was an organ of the Central Committee of the Communist Party of the Soviet Union, Central Committee of the CPSU between 1912 and 1991. After the dissolution of the Soviet Union ''Pravda'' was sold off by President of Russia, Russian President Boris Yeltsin to a Greek business family in 1996, and the paper came under the control of their private company Pravda International. In 1996, there was an internal dispute between the owners of Pravda International and some of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. The purpose of electronic warfare is to deny the opponent the advantage of—and ensure friendly unimpeded access to—the EM spectrum. EW can be applied from air, sea, land, and/or space by crewed and uncrewed systems, and can target communication, radar, or other military and civilian assets. The electromagnetic environment Military operations are executed in an information environment increasingly complicated by the electromagnetic spectrum. The electromagnetic spectrum portion of the information environment is referred to as the electromagnetic environment (EME). The recognized need for military forces to have unimpeded access to and use of the electromagnetic environment creates vulnerabilities and opportunities for electronic warfare in support of military operations.
