VNIIRT
VNIIRT - All-Russian Scientific Research Institute of Radio Engineering (russian: Всероссийский НИИ Радиотехники) is a Russian manufacturer of air surveillance radars. It is part of the Almaz-Antey holding. VNIIRT is the primary Russian designer of ground-based air surveillance radars. It performs scientific research and experimental design work on radars for both the strategic air defense forces and for the ground forces. It has devoted much attention to metric-band (VHF) radars, which have inherent counter-stealth capabilities and are relatively unaffected by meteorological obscuration. VNIIRT's products also have application to civil air traffic control. *1955; P-15 P15 may refer to: * Aviatik P.15, a German reconnaissance biplane * CDKN2B, a human protein * Lippisch P.15, a German prototype aircraft * MAB PA-15 pistol * Nissan Kicks (P15), a SUV * P-15 radar, a Soviet radar system * P15 road (Ukraine) * P-1 ... 1RL13 Tropa FLAT FACE A, UHF (B/C-b ...

Russian Armed Forces
The Armed Forces of the Russian Federation (, ), commonly referred to as the Russian Armed Forces, are the military forces of Russia. In terms of active-duty personnel, they are the world's fifth-largest military force, with at least two million reserve personnel. Their branches consist of the Ground Forces, the Navy, and the Aerospace Forces, as well as three independent arms of service: the Strategic Rocket Forces, the Airborne Forces, and the Special Operations Forces. In 2021, Russia had the world's fifth-highest military expenditure at . The Russian Armed Forces possess the world's largest stockpile of nuclear weapons. They operate the second-largest fleet of ballistic missile submarines, and are one of only three national militaries (alongside those of the United States and China) that operate strategic bombers. With certain exceptions, Russian law mandates one year of military service for all male citizens aged 18–27, though conscripts are generally not depl ...

L Band
The L band is the Institute of Electrical and Electronics Engineers (IEEE) designation for the range of frequencies in the radio spectrum from 1 to 2 gigahertz (GHz). This is at the top end of the ultra high frequency (UHF) band, at the lower end of the microwave range. Applications Mobile service In Europe, the Electronic Communications Committee (ECC) of the European Conference of Postal and Telecommunications Administrations (CEPT) has harmonized part of the L band (1452–1492 MHz), allowing individual countries to adopt this spectrum for terrestrial mobile/fixed communications networks supplemental downlink (MFCN SDL). By means of carrier aggregation, an LTE-Advanced or UMTS/HSDPA base station could use this spectrum to provide additional bandwidth for communications from the base station to the mobile device; i.e., in the downlink direction. In the Americas, mobile services are operated between the 1.7 GHz to 2.1 GHz range in the PCS and AWS bands. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Electronically Scanned Array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled array antenna in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased array technology. PESAs can only emit a single beam of radio waves at a single frequency at a time. The PESA must utilize a Butler matrix ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Defense
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraf ...

Warning Systems
Warning system is any system of biological or technical nature deployed by an individual or group to inform of a future danger. Its purpose is to enable the deployer of the warning system to prepare for the danger and act accordingly to mitigate or avoid it. Warnings cannot be effective unless people react to them. People are more likely to ignore a system that regularly produces false warnings (the cry-wolf effect), but reducing the number of false warnings generally also increases the risk of not giving a warning when it is needed. Some warnings are non-specific: for instance, the probability of an earthquake of a certain magnitude in a certain area over the next decade. Such warnings cannot be used to guide short-term precautions such as evacuation. Opportunities to take long-term precautions, such as better building codes and disaster preparedness, may be ignored. Biological warning systems *Aposematism (e.g. warning coloration) * Climate canary *Fear * Miner's canary *Pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
