Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Passive Electronically Scanned Array
A passive electronically scanned array (PESA), also known as passive phased array, is an antenna in which the beam of radio waves can be electronically steered to point in different directions (that is, a phased array antenna), in which all the antenna elements are connected to a single transmitter (such as a magnetron, a klystron or a travelling wave tube) and/or receiver. The largest use of phased arrays is in radars. Most phased array radars in the world are PESA. The civilian microwave landing system uses PESA transmit-only arrays. A PESA contrasts with an active electronically scanned array (AESA) antenna, which has a separate transmitter and/or receiver unit for each antenna element, all controlled by a computer; AESA is a more advanced, sophisticated versatile second-generation version of the original PESA phased array technology. Hybrids of the two can also be found, consisting of subarrays that individually resemble PESAs, where each subarray has its own RF front e ...

Low-probability-of-intercept Radar
A low-probability-of-intercept radar (LPIR) is a radar employing measures to avoid detection by passive radar detection equipment (such as a radar warning receiver (RWR), or electronic support receiver) while it is passive radar#Target detection, searching for a target or engaged in passive radar#Line tracking, target tracking. This characteristic is desirable in a radar because it allows finding and tracking an opponent without alerting them to the radar's presence. This also protects the radar installation from anti-radiation missiles (ARMs). LPI measures include: *Power management and high duty cycle, meaning the transmitter is on most of the time (long integration times) *Wide bandwidth (or Ultra-wideband) *Frequency agility, and frequency selection *Advanced/irregular scan patterns *Coded pulses (coherent detection) *High processing gain *Low sidelobe antennas Rationale Radar systems work by sending out a signal and then listening for its echo off distant objects.

GLOBUS
GLOBUS is a radar system in the town of Vardø in Vardø Municipality, Finnmark county, Norway. It is operated by the Norwegian Intelligence Service (NIS) and its official uses are primarily space observation and Arctic airspace monitoring for Norway's national interest, though the site's close proximity to known Russian naval bases as well as U.S. involvement in construction and funding have fueled suspicions that it also serves as part of an American missile defense system. History Cold War and Globus I Norway and the United States, both founding members of the newly-formed NATO, began cooperation on the GLOBUS project during the Cold War era of the 1950s. By 1988, the Globus I radar array was built and operational in the town of Vardø, just from the border between Norway and the Soviet Union and within visible range of the Kola Peninsula, which is known to contain high-security Russian naval bases. This came within the same year that the U.S. condemned the deployment of a larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 contrac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flycatcher (radar)
The Flycatcher (KL/MSS-6720) radarsystem is a dual I/J/K-Band short range air defense fire control system. It has an all-weather capability and track-while-scan capability and can simultaneously control three anti-aircraft guns or SAM rocket launchers. The radar system used in the Flycatcher is identical to the system used in the PRTL/Cheetah, the Dutch version of the self-propelled anti-aircraft gun Gepard. The Goalkeeper CIWS uses a similar radar system. The Flycatcher was developed by Hollandse Signaal Apparaten B.V. or in short Signaal or HSA (now Thales Nederland) as successor for their successful L4/5 (KL/MSS-3012) fire control system. Description The Flycatcher system is contained within a towed trailer. Mounted on the roof of it are a search radar and a tracking radar with coaxial passive daylight TV tracking system. The Flycatcher system is built into a standard military Craig container, with a semi-detachable trailer bogey. The antennas are retractable to fac ...

Jane's
Janes is a global open-source intelligence company specialising in military, national security, aerospace and transport topics, whose name derives from British author Fred T. Jane. History Jane's Information Group was founded in 1898 by Fred T. Jane, who had begun sketching ships as an enthusiast naval artist while living in Portsmouth. This gradually developed into an encyclopedic knowledge, culminating in the publishing of ''All the World's Fighting Ships'' (1898). The company then gradually branched out into other areas of military expertise. The books and trade magazines published by the company are often considered the ''de facto'' public source of information on warfare and transportation systems. Based in Greater London for most of its existence, the group was owned by the Thomson Corporation, the Woodbridge Company, then IHS Markit, before being acquired by Montagu Private Equity in 2019. In March 2022, Janes acquired Washington, D.C.-based RWR Advisory Group. Desc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erieye
The Erieye radar system is an Airborne Early Warning and Control System (AEW&C) developed by Saab Electronic Defence Systems, formerly Ericsson Microwave Systems, of Sweden. It uses active electronically scanned array (AESA) technology. The Erieye is used on a variety of aircraft platforms, such as the Saab 340 and Embraer R-99. It has recently been implemented on the Bombardier Global 6000 aircraft as the GlobalEye.

Incoherent Scatter
Incoherent scattering is a type of scattering phenomenon in physics. The term is most commonly used when referring to the scattering of an electromagnetic wave (usually light or radio frequency) by random fluctuations in a gas of particles (most often electrons). The most well known practical application is known as incoherent scatter radar theory, a ground-based technique for studying the Earth's ionosphere first proposed by Professor William E. Gordon in 1958. A radar beam scattering off electrons in the ionospheric plasma creates an incoherent scatter return. When an electromagnetic wave is transmitted through the atmosphere, each of the electrons in the ionospheric plasma essentially acts as an antenna excited by the incoming wave, and the wave is re-radiated from the electron. Since the electrons are all moving at varying speeds as a result of ionospheric dynamics and random thermal motion, the reflection from each electron is also Doppler shifted. The receiver on the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EISCAT
EISCAT (European Incoherent Scatter Scientific Association) operates three incoherent scatter radar systems in Northern Scandinavia and Svalbard. The facilities are used to study the interaction between the Sun and the Earth as revealed by disturbances in the ionosphere and magnetosphere. The EISCAT Scientific Association exists to provide scientists with access to incoherent scatter radar facilities of the highest technical standard. EISCAT 3D The construction of EISCAT's new generation of incoherent radars: EISCAT 3D, has started in November 2022. The first stage of the new system will consist of three radar sites, functioning together, just as the old mainland system. Later, transmitter up grade and more sites will be added to the system. Instead of parabolic dishes, as the old system, EISCAT 3D is a multistatic radar composed of three phased-array antenna fields. Many small antennas working together as one. Each field will have between 5 000 - 10 000 crossed dipole ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Counter-battery Radar
A counter-battery radar or weapon tracking radar is a radar system that detects artillery projectiles fired by one or more guns, howitzers, Mortar (weapon), mortars or rocket launchers and, from their trajectories, locates the position on the ground of the weapon that fired it. Such radars are a subclass of the wider class of target acquisition radars. Early counter-battery radars were generally used against mortars, whose lofted trajectories were highly symmetrical and allowed easy calculation of the launcher's location. Starting in the 1970s, digital computers with improved calculation capabilities allowed more complex trajectories of long-range artillery to also be determined. Normally, these radars would be attached to friendly artillery units or their support units, allowing them to quickly arrange counter-battery fire. With the aid of modern communications systems, the information from a single radar can be rapidly disseminated over long distances. This allows the radar t ...
