Bnei Brak
Bnei Brak or Bene Beraq ( he, בְּנֵי בְּרַק ) 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 (1752 acres, or 2.74 square miles), and had a population of in . It is one of the poorest and most densely populated cities in Israel, and the 5th-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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves 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 information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

1982 Lebanon War
The 1982 Lebanon War, dubbed Operation Peace for Galilee ( he, מבצע שלום הגליל, or מבצע של"ג ''Mivtsa Shlom HaGalil'' or ''Mivtsa Sheleg'') by the Israeli government, later known in Israel as the Lebanon War or the First Lebanon War ( he, מלחמת לבנון הראשונה, ''Milhemet Levanon Harishona''), and known in Lebanon as "the invasion" ( ar, الاجتياح, ''Al-ijtiyāḥ''), began on 6 June 1982, when the Israel Defense Forces (IDF) 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 IDF that had caused civilian casualties on both sides of the border. The military operation was launched after Abu Nidal Organization, gunmen from Abu Nidal's organization attempted to assassinate Shlomo Argov, Israel's ambassador to the United Kingdom. Israeli Prime Minister Menachem Begin blamed Abu Nidal's enemy, the PLO, for the inciden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tadiran Mastiff
The Tadiran Mastiff is a battlefield UAV built by Tadiran Electronic Industries, regarded by some military historians as the world's first modern military 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 It 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 7 hours and real-time video streaming gave Israeli forces unprecedented depth of coverage, speed of information delivery and on-station surveillance time. As a result of the 1973 Yom Kippur War the Israeli Defence Forces came with an operational requirement to give the field commanders the ability to lo ...

Infrared
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates 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 emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar Jamming And Deception
Radar jamming and deception is a form of electronic countermeasures 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 counter-countermeasures can sometimes he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lidar
Lidar (, also LIDAR, or LiDAR; sometimes LADAR) is a method for determining ranges (variable distance) by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver. It can also be used to make digital 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. It has terrestrial, airborne, and mobile applications. ''Lidar'' is an acronym of "light detection and ranging" or "laser imaging, detection, and ranging". It is sometimes called 3-D laser scanning, a special combination of 3-D scanning and laser scanning. Lidar 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 swath mapping (ALSM), and laser altimetry. It is also used in control and navigation for som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surveillance
Surveillance is the monitoring of behavior, many activities, or information for the purpose of information gathering, influencing, managing or directing. This can include observation from a distance by means of electronic equipment, such as closed-circuit television (CCTV), or interception of electronically transmitted information like Internet traffic. It can also include simple technical methods, such as Human intelligence (intelligence gathering), human intelligence gathering and postal interception. Surveillance is used by citizens for protecting their neighborhoods. And by governments for intelligence gathering - including espionage, prevention of crime, the protection of a process, person, group or object, or the investigation of crime. It is also used by criminal organizations to plan and commit crimes, and by businesses to Industrial espionage, gather intelligence on criminals, their competitors, suppliers or customers.

Missile
In military terminology, a missile is a guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles are thus also called guided missiles or guided rockets (when a previously unguided rocket is made guided). Missiles have five system components: targeting, guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles (ballistic, cruise, anti-ship, anti-submarine, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Unguided jet- or rocket-propelled weapons are usually described as rocket artillery. Historically, the word ''missile'' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still ...
