P-20 Radar
The P-20 "Periskop" (; ), also referred to by the NATO reporting name "Token" in the west, is a 2D E band/ F band radar developed and operated by the former Soviet Union. Development The P-20 development was started in 1946 when State Federal Order of the Red Banner Research Institute Number 20 (now called All-Union Scientific Research Institute of Radio Engineering or VNIIRT) was given the task of developing stationary and mobile early warning ground control and interception radar for the Soviet Air Force. The stationary radar later became the P-50 but the mobile radar was to become the P-20. The design inspired a number of successors including the P-30, P-35 and P-37 radar. The P-20 was the first Russian radar to use the decimetric wavelength, the first prototype being created in 1947, and a factory test unit in 1949. By 1949 the radar had completed state trials and was accepted into wide service within the Soviet airforce, the designers of the P-20 were awarded the Sta ...

Periscope
A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle. This form of periscope, with the addition of two simple lenses, served for observation purposes in the trenches during World War I. Military personnel also use periscopes in some gun turrets and in Armored car (military), armoured vehicles. More complex periscopes using Prism (optics), prisms or advanced Optical fiber, fiber optics instead of mirrors and providing magnification operate on submarines and in various fields of science. The overall design of the classical submarine periscope is very simple: two telescopes pointed into each other. If the two telescopes have different individual magnification, the difference between them causes an overall magnification or reduction. ...

Transmission (telecommunications)
In telecommunications, transmission (sometimes abbreviated as "TX") is the process of sending or propagating an Analog signal, analog or digital signal via a transmission medium, medium that is wired communication, wired, wireless, or fiber-optic communication, fiber-optic. Transmission system technologies typically refer to physical layer protocol duties such as modulation, demodulation, line coding, Equalization (communications), equalization, error control, bit synchronization and multiplexing, but it may also involve higher-layer protocol duties, for example, digitizing an analog signal, and data compression. Transmission of a digital message, or of a digitized analog signal, is known as data transmission. Examples of transmission are the sending of signals with limited duration, for example, a block or Network packet, packet of data, a phone call, or an email.

Parabolic Antenna
A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish. The main advantage of a parabolic antenna is that it has high directivity. It functions similarly to a searchlight or flashlight reflector to direct radio waves in a narrow beam, or receive radio waves from one particular direction only. Parabolic antennas have some of the highest gains, meaning that they can produce the narrowest beamwidths, of any antenna type. In order to achieve narrow beamwidths, the parabolic reflector must be much larger than the wavelength of the radio waves used, so parabolic antennas are used in the high frequency part of the radio spectrum, at UHF and microwave ( SHF) frequencies, at which the wavelengths are small enough that conveniently sized reflectors can be used. Parabolic antennas a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ZIS-151
The ZIS-151 () was a general-purpose truck produced by the Soviet Union, Soviet car manufacturer ZiL, Automotive Factory No. 2 ''Zavod imeni Stalina'' in 1948–1958. In 1956, the factory was renamed to ''Zavod imeni Likhacheva'', and new trucks were called ZIL-151 (). The ZIS-151 was the first major Soviet military all-wheel-drive truck built following World War II, replacing the imported U.S. Studebaker US6 and the earlier Soviet ZIS-6. In early 1948, the cabs were made of wood, soon replaced with a steel cab. Tens of thousands were produced, including specialized versions for hauling different types of cargo. The Soviets also found the trucks an ideal platform for BM-13 ''Katyusha'' rocket launchers. The most famous developments of ZIS-151 were the BTR-152 armored personnel carrier and the BAV 485 amphibious vehicle. Due to de-Stalinization the ZIS-151 was renamed in 1956 to ZIL-151. In 1958, an improved model, the ZIL-157, was introduced and replaced the ZIS-151. It diff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NATO Reporting Name
NATO uses a system of code names, called reporting names, to denote military aircraft and other equipment used by post-Soviet states, former Warsaw Pact countries, China, and other countries. The system assists military communications by providing short, one- or two-syllable names, as alternatives to the precise proper names, which may be easily confused under operational conditions or are unknown in the Western world. The assignment of reporting names is managed by the Five Eyes Air Force Interoperability Council (AFIC), previously known as the Air Standardization Coordinating Committee (ASCC), which is separate from NATO. Based in Washington DC, AFIC comprises representatives from the militaries of three NATO members (Canada, the United Kingdom and United States) and two non-NATO countries (Australia and New Zealand). When the system was introduced in the 1950s, reporting names also implicitly designated potentially hostile aircraft. However, since the end of the Cold War, ...

Soviet Air Force
The Soviet Air Forces (, VVS SSSR; literally "Military Air Forces of the Union of Soviet Socialist Republics"; initialism VVS, sometimes referred to as the "Red Air Force") were one of the air forces of the Soviet Union. The other was the Soviet Air Defence Forces. The Air Forces were formed from components of the Imperial Russian Air Service in 1917, and faced their greatest test during World War II. The groups were also involved in the Korean War, and dissolved along with the Soviet Union itself in 1991–92. Former Soviet Air Forces' assets were subsequently divided into several air forces of former Republics of the Soviet Union, Soviet republics, including the new Russian Air Force. The "Air March, March of the Pilots" was its marching song. Origins The first military aviation branch of Russia or any of the Soviet Union's constituent states was the short-lived Imperial Russian Air Service, founded in 1912 and disbanded in 1917 with the onset of the Bolshevik Revolution and ...
