Sevom Khordad
The Sevom Khordad or 3rd Khordad is an Iranian road-mobile medium range air defense missile system that was first unveiled on 11 May 2014. It is believed to be an upgraded version of the Ra'ad air defense system and somewhat superior to the other version of Ra'ad, Tabas (air defense system), although it is more similar to the Ra'ad then the Tabas is. Its operational capabilities were confirmed when it shot down an American Northrop Grumman RQ-4 Global Hawk near the Strait of Hormuz. It is named after the Liberation of Khorramshahr which occurred on 3rd Khordad on the Persian Calendar. Characteristics It shows somewhat resemblance to the Buk-M2. In terms of performance, it is "often compared to the Russian Buk family." Each Sevom Khordad TELAR can carry 3 Taer-2B missiles which have range of 50–105 km and can operate at altitudes of 25–30 km. The Sevom Khordad utilizes an X-band Active Phased array engagement radar, each 3rd Khordad TELAR can simultaneously detec ...

Transporter Erector Launcher
A transporter erector launcher (TEL) is a missile vehicle with an integrated tractor unit that can carry, elevate to firing position and launch one or more missiles. History Such vehicles exist for both surface-to-air missiles and surface-to-surface missiles. Early on, such missiles were launched from fixed sites and had to be loaded onto trucks for transport, making them more vulnerable to attack, since once they were spotted by the enemy they could not easily be relocated, and if they were it often took hours or even days to prepare them for launch once they reached their new site. Usually a number of TELs and TELARs are linked to one command post vehicle (CP or CPV). They may use target information from target acquisition, designation and guidance radar (TADAGR or TAR). Transporter erector launcher and radar A transporter erector launcher and radar (TELAR) is a type of TEL that also incorporates part or all of the radar system necessary for firing the surface-to-air missil ...

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] |
21st-century Surface-to-air Missiles
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emperor, ...

Surface-to-air Missiles Of Iran
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. This evolution of design increasing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syrian Air Defense Force
The Syrian Air Defense Force (SyADF), officially the Syrian Arab Air Defense Force ( ar, قوات الدفاع الجوي العربي السوري) is an independent command within the Syrian Armed Forces. It is responsible for protecting the Syrian airspace against any hostile air attacks. The SyADF is one of the most powerful and combat-tested air defence forces in the region. It has been merged into and then separated from both the Syrian Arab Army and the Syrian Arab Air Force. The Syrian Air Defense Force controls four air defense corps, eleven air defense divisions and thirty-six air defense brigades, each with six surface-to-air missile battalions. Since 2017, it has been linked to a joint Russian-Syrian command. It is equipped with 650 static S-75 Dvina, S-125 Neva/Pechora and S-200 launchers, 300 mobile 2K12 Kub, Pantsir S-1 and Buk launchers and over 4,000 anti-aircraft guns ranging from 23mm to 100mm in caliber (e.g. ZSU-23-4 Shilka).

Islamic Revolutionary Guard Corps Aerospace Force
The Islamic Revolutionary Guard Corps Aerospace Force or Islamic Revolutionary Guard Corps Air and Space Force (IRGCASF; fa, نیروی هوافضای سپاه پاسداران انقلاب اسلامی, niru-ye havâfazây-e sepâh-e pâsdârân-e enghelâb-e eslâmi, officially acronymed NEHSA) is the strategic missile, air, and space force within the Islamic Revolutionary Guard Corps (IRGC) of Iran. It was renamed from the IRGC Air Force into the IRGC Aerospace Force in 2009. Aviation forces Most American public sources disagree and argue on which aircraft are operated by the AFAGIR. The Washington Institute for Near East Policy said in 2005 that " e backbone of the IRGCAF consists of ten Su-25 Frogfoot attack aircraft (including seven flown from Iraq to Iran during the 1991 Gulf War, kept airworthy with the help of Georgian technicians) and around forty EMB-312 Tucanos". The Washington Institute also said that the IRGCAF maintained thirty Y-12 and Dassault Falcon 20 li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar Jamming
Radar jamming and deception is a form of electronic countermeasures that intentionally sends out radio frequency signals to interfere with the operation of radar by saturating its receiver with noise or false information. Concepts that blanket the radar with signals so its display cannot be read are normally known as jamming, while systems that produce confusing or contradictory signals are known as deception, but it is also common for all such systems to be referred to as jamming. There are two general classes of radar jamming, mechanical and electronic. Mechanical jamming entails reflecting enemy radio signals in various ways to provide false or misleading target signals to the radar operator. Electronic jamming works by transmitting additional radio signals towards enemy receivers, making it difficult to detect real target signals, or take advantage of known behaviors of automated systems like radar lock-on to confuse the system. Various counter-countermeasures can sometimes he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tactical Data Link
A tactical data link (TDL) uses a data link standard in order to provide communication via radio waves or cable used by NATO nations. All military C3 systems use standardized TDL to transmit, relay and receive tactical data. Multi-TDL network (MTN) refers to the network of similar and dissimilar TDLs integrated through gateways, translators, and correlators to bring the common tactical picture and/or common operational picture together. Change of terminology The term ''tactical digital information link (TADIL)'' was made obsolete (per DISA guidance) and is now more commonly seen as ''tactical data link (TDL)''. Tactical data link character TDLs are characterized by their standard message and transmission formats. This is usually written as <Message Format>/<Transmission Format>. TDL standards in NATO In NATO, tactical data link standards are being developed by the ''Data Link Working Group (DLWG)'' of the ''Information Systems Sub-Committee (ISSC)'' in li ...

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 ...

Phased Array
In antenna theory, a phased array usually means an electronically scanned array, a computer-controlled array of antennas which creates a beam of radio waves that can be electronically steered to point in different directions without moving the antennas. In a simple array antenna, the radio frequency current from the transmitter is fed to multiple individual antenna elements with the proper phase relationship so that the radio waves from the separate elements combine ( superpose) to form beams, to increase power radiated in desired directions and suppress radiation in undesired directions. In a phased array, the power from the transmitter is fed to the radiating elements through devices called ''phase shifters'', controlled by a computer system, which can alter the phase or signal delay electronically, thus steering the beam of radio waves to a different direction. Since the size of an antenna array must extend many wavelengths to achieve the high gain needed for narrow bea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S-band
The S band is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a part of the microwave band of the electromagnetic spectrum covering frequencies from 2 to 4 gigahertz (GHz). Thus it crosses the conventional boundary between the UHF and SHF bands at 3.0 GHz. The S band is used by airport surveillance radar for air traffic control, weather radar, surface ship radar, and some communications satellites, especially those used by NASA to communicate with the Space Shuttle and the International Space Station. The 10 cm radar short-band ranges roughly from 1.55 to 5.2 GHz. The S band also contains the 2.4–2.483 GHz ISM band, widely used for low power unlicensed microwave devices such as cordless phones, wireless headphones (Bluetooth), wireless networking (WiFi), garage door openers, keyless vehicle locks, baby monitors as well as for medical diathermy machines and microwave ovens (typically at 2.495 GHz).
