TPY-2
The AN/TPY-2 Surveillance Transportable Radar, also called the Forward Based X-Band Transportable (FBX-T) is a long-range, very high-altitude active digital antenna array X band surveillance radar designed to add a tier to existing missile and air defence systems. It has a range of . Made by Raytheon, it is the primary radar for the Terminal High Altitude Area Defense (THAAD) missile system, but also cues the AN/MPQ-53 radar of the MIM-104 Patriot system. Patriot PAC-3 is a lower-altitude missile and air defense system than THAAD. The AN/TPY-2 is a missile-defense radar that can detect, classify, track and intercept ballistic missiles. It has two operating modes – one to detect ballistic missiles as they rise, and another that can guide interceptors toward a descending warhead. Once it detects the missile, it acquires it, tracks it, and uses its powerful radar and complex computer algorithms to discriminate between the warhead and non-threats such as countermeasures in order ...

Terminal High Altitude Area Defense
Terminal High Altitude Area Defense (THAAD), formerly Theater High Altitude Area Defense, is an American anti-ballistic missile defense system designed to shoot down short-, medium-, and intermediate-range ballistic missiles in their terminal phase (descent or reentry) by intercepting with a hit-to-kill approach. THAAD was developed after the experience of Iraq's Scud missile attacks during the Gulf War in 1991. The THAAD interceptor carries no warhead, instead relying on its kinetic energy of impact to destroy the incoming missile. Originally a United States Army program, THAAD has come under the umbrella of the Missile Defense Agency. The Navy has a similar program, the sea-based Aegis Ballistic Missile Defense System, which also has a land component ("Aegis Ashore"). THAAD was originally scheduled for deployment in 2012, but initial deployment took place in May 2008. THAAD has been deployed in the United Arab Emirates, Israel, Romania, and South Korea. On 17 January 2022, ... [...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 ...

United States National Missile Defense
National missile defense (NMD) is a generic term for a type of missile defense intended to shield an entire country against incoming missiles, such as intercontinental ballistic missile (ICBMs) or other ballistic missiles. This is also used to refer to the American nationwide antimissile program the United States has had in development since the 1990s. After the renaming in 2002, the term now refers to the entire program, not just the ground-based interceptors and associated facilities. This article focuses mainly on this system and a brief history of earlier systems which led to it. Other elements that could potentially be integrated into NMD include anti-ballistic missiles, or sea-based, space-based, laser, and high altitude missile systems. The NMD program is limited in scope and designed to counter a relatively small ICBM attack from a less sophisticated adversary. Unlike the earlier Strategic Defense Initiative program, it is not designed to be a robust shield agains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIM-104 Patriot
The MIM-104 Patriot is a surface-to-air missile (SAM) system, the primary of its kind used by the United States Army and several allied states. It is manufactured by the U.S. defense contractor Raytheon and derives its name from the radar component of the weapon system. The AN/MPQ-53 at the heart of the system is known as the " Phased Array Tracking Radar to Intercept on Target", or PATRIOT. The Patriot system replaced the Nike Hercules system as the U.S. Army's primary High to Medium Air Defense (HIMAD) system and replaced the MIM-23 Hawk system as the U.S. Army's medium tactical air defense system. In addition to these roles, Patriot has been given the function of the U.S. Army's anti-ballistic missile (ABM) system, which is now Patriot's primary mission. The system is expected to stay fielded until at least 2040. Patriot uses an advanced aerial interceptor missile and high-performance radar systems.

Arrow (Israeli Missile)
The Arrow or ''Hetz'' ( he , חֵץ, ) is a family of anti-ballistic missiles designed to fulfill an Israeli requirement for a missile defense, missile defense system that would be more effective against ballistic missiles than the MIM-104 Patriot surface-to-air missile. Jointly funded and produced by Israel and the United States, development of the system began in 1986 and has continued since, drawing some contested criticism. Undertaken by the MALAM division of the Israel Aerospace Industries (IAI) and Boeing, it is overseen by the Ministry of Defense (Israel), Israeli Ministry of Defense's "''Homa'' ( he, חומה, , "Defensive wall, rampart") administration and the U.S. Missile Defense Agency. It forms the long-range layer of Israel's multi-tiered missile defence system, along with David's Sling (at medium-to-long range) and both Iron Dome and Iron Beam (at short ranges). The Arrow system consists of the joint production hypersonic Arrow anti-missile interceptors, Arrow 2 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X Band
The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum. In some cases, such as in communication engineering, the frequency range of the X band is rather indefinitely set at approximately 7.0–11.2 GHz. In radar engineering, the frequency range is specified by the Institute of Electrical and Electronics Engineers (IEEE) as 8.0–12.0 GHz. The X band is used for radar, satellite communication, and wireless computer networks. Radar X band is used in radar applications including continuous-wave, pulsed, single- polarization, dual-polarization, synthetic aperture radar, and phased arrays. X band radar frequency sub-bands are used in civil, military, and government institutions for weather monitoring, air traffic control, maritime vessel traffic control, defense tracking, and vehicle speed detection for law enforcement. X band is often used in modern radars. The shorter wavelengths of the X band allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves 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 information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

FBX T
FBX (''Filmbox'') is a proprietary file format () developed by Kaydara and owned by Autodesk since 2006. It is used to provide interoperability between digital content creation applications. FBX is also part of Autodesk Gameware, a series of video game middleware. History FBX originated as a replacement file format for Canadian company Kaydara's Filmbox, a software for recording data from motion capture devices. Prior to 1996, Filmbox 1.0 used a file format called FLM. The format only supported motion data, user preferences and a list of devices used in the capturing of the motion data. This data was a serialized version of the libraries (binary dump), containing read/write memory data. This method of storing data did not work well with different versions of Filmbox. There was also demand from early adopters of Filmbox to implement a target character in a scene with the motion capture data, to enable the visualization of the data in a 3D view with display markers. In 1996, Ka ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Air Defense Artillery
The Air Defense Artillery Branch is the branch of the United States Army that specializes in anti-aircraft weapons (such as surface to air missiles). In the U.S. Army, these groups are composed of mainly air defense systems such as the Patriot Missile System, Terminal High Altitude Area Defense (THAAD), and the Avenger Air Defense system which fires the FIM-92 Stinger missile. The Air Defense Artillery branch descended from Anti-Aircraft Artillery (part of the U.S. Army Coast Artillery Corps until 1950, then part of the Artillery Branch) into a separate branch on 20 June 1968. On 1 December 1968, the ADA branch was authorized to wear modified Artillery insignia, crossed field guns with missile. The Branch Motto, "First To Fire", was adopted in 1986 by the attendees of the ADA Commanders' Conference at Fort Bliss. The motto refers to a speech given by General Jonathan Wainwright to veterans of the 200th Coast Artillery (Antiaircraft) stating they were the 'First to Fire' i ...
