Asr (radar)
Asr ( fa, رادار عصر Radar) is an Iranian passive electronically scanned array long-range radar unveiled in 2013. The Air Surveillance Radar or ASR is a 3-D solid state phased array radar, capable of detecting boats, low flying aircraft with a radar cross section (RCS) of at a range of . The radar is jointly designed and built by the Islamic Republic of Iran Navy and the Ministry of Defence and Armed Forces Logistics (Iran) The Ministry of Defence and Armed Forces Logistics (MODAFL; fa, وزارت دفاع و پشتیبانی نیروهای مسلح, vezarat-e defa' va poshtibani-ey niruha-ye mosallah) is the defence ministry of the Islamic Republic of Iran and pa .... Specifications The indigenous ASR naval radar uses a passive electronically scanned array, which can be deployed on shore or on ships, making it less vulnerable to anti-radar missiles that use radar signals to home in on their target. Ceremony The "Asr" radar was unveiled at a ceremony attended by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Phased Array Radar
A phaser is an electronic sound processor used to filter a signal, and it has a series of troughs in its frequency-attenutation graph. The position (in Hz) of the peaks and troughs are typically modulated by an internal low-frequency oscillator so that they vary over time, creating a sweeping effect. Phasers are often used to give a "synthesized" or electronic effect to natural sounds, such as human speech. The voice of C-3PO from ''Star Wars'' was created by taking the actor's voice and treating it with a phaser. Process The electronic phasing effect is created by splitting an audio signal into two paths. One path treats the signal with an all-pass filter, which preserves the amplitude of the original signal and alters the phase. The amount of change in phase depends on the frequency. When signals from the two paths are mixed, the frequencies that are out of phase will cancel each other out, creating the phaser's characteristic notches. Changing the mix ratio changes the d ...

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 ...

Ministry Of Defence And Armed Forces Logistics (Iran)
The Ministry of Defence and Armed Forces Logistics (MODAFL; fa, وزارت دفاع و پشتیبانی نیروهای مسلح, vezarat-e defa' va poshtibani-ey niruha-ye mosallah) is the defence ministry of the Islamic Republic of Iran and part of the country's executive branch. It thus reports to the President of Iran, not to the Commander-in-Chief of the Iranian Armed Forces. Unlike many countries, the ministry is not involved with in-the-field military operational command of the armed forces. Instead it is responsible for planning, logistics and funding of the Armed Forces of the Islamic Republic of Iran while the General Staff, a separate institution under command of the supreme leader of Iran, has control over the forces. The MODAFL is also the major player in defense industry of Iran, with multiple conglomerates and subordinates active in research and development, maintenance and manufacturing of military equipment. It annually exports military equipment manufactured i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military Radars Of Iran
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
