Matla-ul-fajr
Matla-ul-fajr (Arabic ''مطلعالفجر'' lit. ''Rise of Dawn'') is an Iranian VHF 3D radar. It was first seen in military parades. It was stated that Matla-ul-fajr covered the whole Persian Gulf. The range of Matla-ul-Fajr-1 is 300 km and the max altitude is 20,000 m. When fully set up, the height of the system reaches eight meters and it uses 12 "Yagi" antennas installed in two rows. The whole system, containing the antennas, setup instruments, processing, controlling and displaying units, communication devices and power generator are all installed on a trailer to achieve a very good mobility. The radar is also equipped with ECCM to survive in an e-warfare environment. Matla-ul-fajr can use 100 different frequencies in the VHF band to operate in jammed environments. In the same year, a project to enhance the capabilities of radar was started by SAIRAN and Isfahan University of Technology. Production of this model called Matla-ul-fajr 2 was started in 2012.

Radar Cross-section
Radar cross-section (RCS), also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. An object reflects a limited amount of radar energy back to the source. The factors that influence this include: *the material with which the target is made; *the size of the target relative to the wavelength of the illuminating radar signal; *the absolute size of the target; *the incident angle (angle at which the radar beam hits a particular portion of the target, which depends upon the shape of the target and its orientation to the radar source); *the reflected angle (angle at which the reflected beam leaves the part of the target hit; it depends upon incident angle); *the polarization of the transmitted and the received radiation with respect to the orientation of the target. While important in detecting targets, strength of emitter and distance are not factors that affect the calculation of an RCS becaus ...

Current Equipment Of The Iranian Army
This page includes weapons used by both the Ground Forces of the Islamic Republic of Iran Army and the Ground Forces of the Islamic Revolutionary Guard Corps. From 1925 to the Iranian Revolution in 1979, Iran was primarily equipped with Western hardware and equipment. Cases exist where Iran was supplied with equipment before it was even made standard in the country that developed it (for example the US F-14 Tomcat jet, and the British Chieftain tank). Primary suppliers included the United States, Britain, France, West Germany, Italy, Israel, and the Soviet Union. The post-revolution sanctions and the Iran–Iraq War had a dramatic effect on Iran's inventory of western equipment. Under the pressures of war, supplies were quickly exhausted and replacements became difficult to come by. The war forced Iran to turn towards Syria, Brazil and China to meet its short-term military needs. Initial developments in military technology were carried out with the support of China, North Kor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iranian Military Industry
Iran's military industry manufactures and exports various types of arms and military equipment. Iran's military industry, under the command of Iran's Ministry of Defence and Armed Forces Logistics, is composed of the following main components: Security of Telecommunication and Information Technology (STI) is also part of the Iranian defense industry. History Iran's military industry was born under the last Shah of Iran, Mohammad Reza Pahlavi. In 1973, the Iran Electronics Industries (IEI) was founded to organize efforts to assemble and repair foreign-delivered weapons. Most of Iran's weapons before the Islamic revolution were imported from the United States and Europe. Between 1971 and 1975, the Shah went on a buying spree, ordering $8 billion in weapons from the United States alone. This alarmed the United States Congress, which strengthened a 1968 law on arms exports in 1976 and renamed it the Arms Export Control Act. Still, the United States continued to sell large amounts ...

Military Of Iran
The Islamic Republic of Iran Armed Forces, are the combined military forces of Iran, comprising the Islamic Republic of Iran Army (''Arteš''), the Islamic Revolutionary Guard Corps (''Sepâh'') and the Law Enforcement Force (Police). Iranian Armed Forces are the largest in the Middle East in terms of active troops. Iran's military forces are made up of approximately 610,000 active-duty personnel plus 350,000 reserve and trained personnel that can be mobilized when needed, bringing the country's military manpower to about 960,000 total personnel. These numbers do not include Law Enforcement Force or Basij. Most of Iran's imported weapons consist of American systems purchased before the 1979 Islamic Revolution, with limited purchases from the Soviet Union in the 1990s following the Iran–Iraq War. However, the country has since then launched a robust domestic rearmament program, and its inventory has become increasingly indigenous. According to Iranian officials, most of ...

Cruise Missile
A cruise missile is a guided missile used against terrestrial or naval targets that remains in the atmosphere and flies the major portion of its flight path at approximately constant speed. Cruise missiles are designed to deliver a large warhead over long distances with high precision. Modern cruise missiles are capable of travelling at high subsonic, supersonic, or hypersonic speeds, are self-navigating, and are able to fly on a non-ballistic, extremely low-altitude trajectory. History The idea of an "aerial torpedo" was shown in the British 1909 film ''The Airship Destroyer'' in which flying torpedoes controlled wirelessly are used to bring down airships bombing London. In 1916, the American aviator Lawrence Sperry built and patented an "aerial torpedo", the Hewitt-Sperry Automatic Airplane, a small biplane carrying a TNT charge, a Sperry autopilot and a barometric altitude control. Inspired by the experiments, the United States Army developed a similar flying bomb cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stealth Aircraft
Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection/emission of radar, infrared, visible light, radio frequency (RF) spectrum, and audio, collectively known as stealth technology. The F-117 Nighthawk was the first operational aircraft specifically designed around stealth technology. Other examples of stealth aircraft include the B-2 Spirit, the B-21 Raider, the F-22 Raptor, the F-35 Lightning II, the Chengdu J-20, and the Sukhoi Su-57. While no aircraft is totally invisible to radar, stealth aircraft make it more difficult for conventional radar to detect or track the aircraft effectively, increasing the odds of an aircraft successfully avoiding detection by enemy radar and/or avoiding being successfully targeted by radar guided weapons. Stealth is the combination of passive low observable (LO) features and active emitters such as low-probability-of-intercept radars, radios and laser designators. These are usually combined ...

Mashregh News
Mashregh News ( fa, مشرقنیوز, ) is a non-governmental news website in Iran. It has been described as "close to the security and intelligence organizations" but till now there have been no clear documents to prove claims. It is based in Tehran. Mashregh News often breaks stories of international interest. In 2010, Mashregh News announced the 19-1/2 year prison sentence given to dissident Canadian-Iranian blogger Hossein Derakhshan. According to Mashregh News, Derakhshan was "convicted of cooperating with enemy states, making propaganda against the Islamic system of government, promoting small anti-revolutionary groups, managing obscene web sites and insulting Islamic sanctities". The agency is known for censoring and altering news images. In 2011, when Sarah Shourd was released from an Iranian prison, Mashregh News blurred the areas of her breasts and arms in photos of her. In January, 2012, Mashregh News broke the story of the six-month prison sentence given to women's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Early-warning Radar
An early-warning radar is any radar system used primarily for the long-range detection of its targets, i.e., allowing defences to be alerted as ''early'' as possible before the intruder reaches its target, giving the air defences the maximum time in which to operate. This contrasts with systems used primarily for tracking or gun laying, which tend to offer shorter ranges but offer much higher accuracy. EW radars tend to share a number of design features that improve their performance in the role. For instance, EW radar typically operates at lower frequencies, and thus longer wavelengths, than other types. This greatly reduces their interaction with rain and snow in the air, and therefore improves their performance in the long-range role where their coverage area will often include precipitation. This also has the side-effect of lowering their optical resolution, but this is not important in this role. Likewise, EW radars often use much lower pulse repetition frequency to maximi ...
