Alim Radar System
Alim is the first Iranian passive radar. Passive radars do not transmit. Instead, they detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals. Alim is cheaper and has lower maintenance cost than conventional radars because it lacks a transmitter and movable mechanical parts. It requires high processing power, as six levels of processing are needed to track targets. Other advantages include the ability to detect low RCS targets at low altitudes. Since it doesn't transmit, it is immune to anti radiation missiles such as American AGM-88 HARM, thus it can be deployed near enemy lines. It was first seen in 2011 during the parade of Iranian armed forces. The radar has a range of between 250 and 300 km and is able to detect slow, low flying targets with relative ease.

Iran
Iran, officially the Islamic Republic of Iran, and also called Persia, is a country located in Western Asia. It is bordered by Iraq and Turkey to the west, by Azerbaijan and Armenia to the northwest, by the Caspian Sea and Turkmenistan to the north, by Afghanistan and Pakistan to the east, and by the Gulf of Oman and the Persian Gulf to the south. It covers an area of , making it the 17th-largest country. Iran has a population of 86 million, making it the 17th-most populous country in the world, and the second-largest in the Middle East. Its largest cities, in descending order, are the capital Tehran, Mashhad, Isfahan, Karaj, Shiraz, and Tabriz. The country is home to one of the world's oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. It was first unified by the Medes, an ancient Iranian people, in the seventh century BC, and reached its territorial height in the sixth century BC, when Cyrus the Great fo ...

Passive Radar
Passive radar systems (also referred to as passive coherent location, passive surveillance systems, and passive covert radar) encompass a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals. It is a specific case of bistatic radar, the latter also including the exploitation of cooperative and non-cooperative radar transmitters. Introduction Conventional radar systems comprise a colocated transmitter and receiver, which usually share a common antenna to transmit and receive. A pulsed signal is transmitted and the time taken for the pulse to travel to the object and back allows the range of the object to be determined. In a passive radar system, there is no dedicated transmitter. Instead, the receiver uses third-party transmitters in the environment and measures the time difference of arrival between the signal arriving directly from ...

Sacred Defence Week Parade, 2011 (95)
Sacred describes something that is dedicated or set apart for the service or worship of a deity; is considered worthy of spiritual respect or devotion; or inspires awe or reverence among believers. The property is often ascribed to objects (a " sacred artifact" that is venerated and blessed), or places (" sacred ground"). French sociologist Émile Durkheim considered the dichotomy between the sacred and the profane to be the central characteristic of religion: "religion is a unified system of beliefs and practices relative to ''sacred things'', that is to say, things set apart and forbidden." Durkheim, Émile. 1915. ''The Elementary Forms of the Religious Life''. London: George Allen & Unwin. . In Durkheim's theory, the sacred represents the interests of the group, especially unity, which are embodied in sacred group symbols, or using team work to help get out of trouble. The profane, on the other hand, involve mundane individual concerns. Etymology The word ''sacred'' des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Anti-radiation Missile
An anti-radiation missile (ARM) is a missile designed to detect and home in on an enemy radio emission source. Typically, these are designed for use against an enemy radar, although jammers and even radios used for communications can also be targeted in this manner. The earliest known anti-radiation weapon is a variant of the Blohm & Voss BV 246 radar guided bomb. Air-to-surface Most ARM designs to date have been intended for use against ground-based radars. Commonly carried by specialist aircraft in the Suppression of Enemy Air Defenses (SEAD) role (known to United States Air Force as "Wild Weasels"), the primary purpose of this type of missile is to degrade enemy air defenses in the first period of a conflict in order to increase the chance of survival for the following waves of strike aircraft. They can also be used to quickly shut down unexpected surface-to-air missile (SAM) sites during an air raid. Often, SEAD escort aircraft also carry cluster bombs, which can be u ...

AGM-88 HARM
The AGM-88 HARM (High-speed Anti-Radiation Missile) is a tactical, air-to-surface anti-radiation missile designed to home in on electronic transmissions coming from surface-to-air radar systems. It was originally developed by Texas Instruments as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system. Production was later taken over by Raytheon Corporation when it purchased the defense production business of Texas Instruments. Description The AGM-88 can detect, attack and destroy a radar antenna or transmitter with minimal aircrew input. The proportional guidance system that homes in on enemy radar emissions has a fixed antenna and seeker head in the missile's nose. A smokeless, solid-propellant, booster-sustainer rocket motor propels the missile at speeds over Mach 2.0. The HARM was a missile program led by the U.S. Navy, and it was first carried by the A-6E, A-7, and F/A-18A/B aircraft, and then it equipped the EA-6B and EA-18G dedicated electronic attack aircraft ...

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 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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of 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] |
