Bnei Brak
Bnei Brak ( ) or Bene Beraq, is a city located on the central Mediterranean Sea, Mediterranean Israeli coastal plain, coastal plain in Israel, just east of Tel Aviv. A center of Haredi Judaism, Bnei Brak covers an area of 709 hectares (1,752 acres, or 2.74 square miles), and had a population of in . It is one of the most densely populated cities in Israel and the fourth-most List of cities by population density, densely populated city in the world. History Bnei Brak takes its name from the ancient Biblical city of Beneberak, mentioned in the Hebrew Bible, Tanakh (Joshua 19:45) in a long list of towns within the allotment of the tribe of Dan. Bnei Brak was founded as an agricultural village by eight Polish Hasidic Judaism, Hasidic families who had come to Palestine as part of the Fourth Aliyah. Yitzchok Gerstenkorn led them. It was founded about 4 kilometers (2.5 miles) from the site of Biblical Beneberak. Bnei Brak was originally a moshava, and the primary economic activity wa ...

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1982 Lebanon War
The 1982 Lebanon War, also called the Second Israeli invasion of Lebanon, began on 6 June 1982, when Israel invaded southern Lebanon. The invasion followed a series of attacks and counter-attacks between the Palestine Liberation Organization (PLO) operating in southern Lebanon and the Israel Defense Forces, Israeli military, which had caused civilian casualties on both sides of the border. The Israeli military operation, codenamed Operation Peace for Galilee, was launched after gunmen from the Abu Nidal Organization attempted to assassinate Shlomo Argov, Israel's ambassador to the United Kingdom. Israeli Prime Minister Menachem Begin blamed the PLO, using the incident as a ''casus belli''. It was the second invasion of Lebanon by Israel, following the 1978 South Lebanon conflict. The Israelis sought to end Palestinian insurgency in South Lebanon, Palestinian attacks from Lebanon, destroy the Palestine Liberation Organization (PLO) in the country, and install a pro-Israel Leban ...

Tadiran Mastiff
The Tadiran Mastiff is a battlefield UAV built by Tadiran Electronic Industries of Israel, and regarded by some military historians as the world's first modern military surveillance drone.The ''Encyclopedia of the Arab-Israeli Conflict: A Political, Social, and Military History: A Political, Social, and Military History'', ABC-CLIO, 12 May 2008, by Spencer C. Tucker, Priscilla Mary Roberts, page 1054-55 ISBN Design and development The Mastiff first flew in 1973. It featured a data-link system and miniaturized electronics that fed live and high-resolution video coverage of the targeted area to operators. It is thus seen by some as the first modern surveillance UAV. The combination of its long flight endurance of over seven hours and real-time video streaming gave Israeli forces unprecedented depth of coverage, speed of information delivery and on-station surveillance time. The Mastiff was powered by a German-made Limbach Flugmotoren two-cylinder, two-stroke motor with thrust gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared
Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. The infrared spectral band begins with the waves that are just longer than those of red light (the longest waves in the visible spectrum), so IR is invisible to the human eye. IR is generally (according to ISO, CIE) understood to include wavelengths from around to . IR is commonly divided between longer-wavelength thermal IR, emitted from terrestrial sources, and shorter-wavelength IR or near-IR, part of the solar spectrum. Longer IR wavelengths (30–100 μm) are sometimes included as part of the terahertz radiation band. Almost all black-body radiation from objects near room temperature is in the IR band. As a form of EMR, IR carries energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires e ...

Radar Jamming And Deception
Radar jamming and deception is a form of electronic countermeasures (ECMs) 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 Electronic counter-countermeasur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lidar
Lidar (, also LIDAR, an acronym of "light detection and ranging" or "laser imaging, detection, and ranging") is a method for determining ranging, ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. Lidar may operate in a fixed direction (e.g., vertical) or it may scan multiple directions, in a special combination of 3-D scanning and laser scanning. Lidar has terrestrial, airborne, and mobile applications. It is commonly used to make high-resolution maps, with applications in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swathe mapping (ALSM), and Mars Orbiter Laser Altimeter, laser altimetry. It is used to make digital 3D modeling, 3-D representations of areas on the Earth's surface and ocean bottom of the intertidal and near coastal zone by varying the wavelength of light.

Missile
A missile is an airborne ranged weapon capable of self-propelled flight aided usually by a propellant, jet engine or rocket motor. Historically, 'missile' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still recognized today with any unguided jet- or rocket-propelled weapons generally described as rocket artillery. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Missiles are also generally guided towards specific targets termed as guided missiles or guided rockets. Missile systems usually have five system components: targeting, guidance system, flight system, engine, and warhead. Missiles are primarily classified into different types based on firing source and target such as surface-to-surface, air-to-surface, surface-to-air and air-to-air missiles. Terminology Missile is derived from Latin "missilis" meaning "that may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
