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), denoted σ, 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 radiation transmitted and received 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Equipment Of The Iranian Army
This page includes weapons used by both the Islamic Republic of Iran Army Ground Forces, Ground Forces of the Islamic Republic of Iran Army and the Islamic Revolutionary Guard Corps Ground Forces, 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), Chieftain tank). Primary suppliers included the United States, United Kingdom, 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 Ba'athist Syria, Syria, Brazil an ...

Defense Industry Of Iran
Iran's military industry manufactures and exports various types of arms and military equipment. Iran's military industry, under the command of Ministry of Defense and Armed Forces Logistics (Iran), 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 Pahlavi dynasty, 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 ...

Cruise Missile
A cruise missile is an unmanned self-propelled guided missile that sustains flight through aerodynamic lift for most of its flight path. Cruise missiles are designed to deliver a large payload over long distances with high precision. Modern cruise missiles are capable of traveling at high Aerodynamics#Incompressible aerodynamics, subsonic, Supersonic speed, supersonic, or Hypersonic speed, hypersonic speeds, are self-navigating, and are able to fly on a non-Ballistics, 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 Americans, American Aircraft pilot, 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 barometric altitude control. Inspired by the experiments, the ... [...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 explicitly designed around stealth technology. Other examples of stealth aircraft include the Northrop Grumman B-2 Spirit, B-2 Spirit, the B-21 Raider, the Lockheed Martin F-22 Raptor, F-22 Raptor, the F-35 Lightning II, the Chengdu J-20, and the Sukhoi Su-57. While no aircraft is completely 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 avoiding detection by enemy radar and/or avoiding being successfully targeted by Semi-active radar guidance, radar guided weapons. Stealth is a combination of passive low observable (LO) features and active emitters such as low-probability-of-interc ... [...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 ...
