Jon Jones Reclaims UFC Belt With Third Round TKO Of Daniel Cormier. Jon Jones reclaimed the UFC light heavyweight title with a third round TKO over rival Daniel Cormier in one of the promotions most anticipated matchups ever. Jones traded even blows with the shorter, older Cormier throughout the first two rounds before staggering the former Olympic wrestler with a kick and ending his two year reign atop the division midway through the third round with a frightening number of blows. It was Joness first bout since returning from a one year doping ban, and the pairs first matchup since Jones defeated Cormier by unanimous decision in 2. Radar Wikipedia.

It rotates steadily, sweeping the airspace with a narrow beam. Radar is an object detection system that uses radio waves to determine the range, angle, or velocity of objects. 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 object and return to the receiver, giving information about the objects location and speed. Radar was developed secretly for military use by several nations in the period before and during World War II. The term RADAR was coined in 1. United States Navy as an acronym for RAdio Detection And Ranging12 or RAdio Direction And Ranging. The term radar has since entered English and other languages as a common noun, losing all capitalization. The modern uses of radar are highly diverse, including air and terrestrial traffic control, radar astronomy, air defence systems, antimissile systems, marine radars to locate landmarks and other ships, aircraft anticollision systems, ocean surveillance systems, outer space surveillance and rendezvous systems, meteorological precipitation monitoring, altimetry and flight control systems, guided missile target locating systems, ground penetrating radar for geological observations, and range controlled radar for public health surveillance. High tech radar systems are associated with digital signal processing, machine learning and are capable of extracting useful information from very high noise levels. Other systems similar to radar make use of other parts of the electromagnetic spectrum. One example is lidar, which uses predominantly infrared light from lasers rather than radio waves. HistoryeditFirst experimentseditAs early as 1. German physicist Heinrich Hertz showed that radio waves could be reflected from solid objects. In 1. 89. 5, Alexander Popov, a physics instructor at the Imperial Russian Navy school in Kronstadt, developed an apparatus using a coherer tube for detecting distant lightning strikes. The next year, he added a spark gap transmitter. In 1. 89. 7, while testing this equipment for communicating between two ships in the Baltic Sea, he took note of an interference beat caused by the passage of a third vessel. In his report, Popov wrote that this phenomenon might be used for detecting objects, but he did nothing more with this observation. The German inventor Christian Hlsmeyer was the first to use radio waves to detect the presence of distant metallic objects. In 1. 90. 4, he demonstrated the feasibility of detecting a ship in dense fog, but not its distance from the transmitter. He obtained a patent8 for his detection device in April 1. He also got a British patent on September 2. Free Download Upgrade App World For Blackberry 9700 Bold Parts there. It operated on a 5. His system already used the classic antenna setup of horn antenna with parabolic reflector and was presented to German military officials in practical tests in Cologne and Rotterdam harbour but was rejected. In 1. 91. 5, Robert Watson Watt used radio technology to provide advance warning to airmen1. U. K. research establishment to make many advances using radio techniques, including the probing of the ionosphere and the detection of lightning at long distances. Through his lightening experiments, Watson Watt became an expert on the use of radio direction finding before turning his inquiry to shortwave transmission. Requiring a suitable receiver for such studies, he told the new boy Arnold Frederic Wilkins to conduct an extensive review of available shortwave units. Wilkins would select a General Post Office model after noting its manuals description of a fading effect the common term for interference at the time when aircraft flew overhead. Across the Atlantic in 1. Potomac River, U. S. Navy researchers A. Hoyt Taylor and Leo C. Young discovered that ships passing through the beam path caused the received signal to fade in and out. Taylor submitted a report, suggesting that this phenomenon might be used to detect the presence of ships in low visibility, but the Navy did not immediately continue the work. Eight years later, Lawrence A. Hyland at the Naval Research Laboratory NRL observed similar fading effects from passing aircraft this revelation led to a patent application1. NRL, where Taylor and Young were based at the time. Just before World War IIeditBefore the Second World War, researchers in the United Kingdom, France, Germany, Italy, Japan, the Netherlands, the Soviet Union, and the United States, independently and in great secrecy, developed technologies that led to the modern version of radar. Australia, Canada, New Zealand, and South Africa followed prewar Great Britains radar development, and Hungary generated its radar technology during the war. In France in 1. 93. Split Anode Magnetron, the research branch of the Compagnie Gnrale de Tlgraphie Sans Fil CSF headed by Maurice Ponte with Henri Gutton, Sylvain Berline and M. Hugon, began developing an obstacle locating radio apparatus, aspects of which were installed on the ocean liner Normandie in 1. During the same period, Soviet military engineer P. K. Oshchepkov, in collaboration with Leningrad Electrophysical Institute, produced an experimental apparatus, RAPID, capable of detecting an aircraft within 3 km of a receiver. The Soviets produced their first mass production radars RUS 1 and RUS 2 Redut in 1. Oshchepkov and his subsequent gulag sentence. In total, only 6. Redut stations were produced during the war. The first Russian airborne radar, Gneiss 2, entered into service in June 1. Pe 2 fighters. More than 2. Gneiss 2 stations were produced by the end of 1. The French and Soviet systems, however, featured continuous wave operation that did not provide the full performance ultimately synonymous with modern radar systems. Full radar evolved as a pulsed system, and the first such elementary apparatus was demonstrated in December 1. American Robert M. Page, working at the Naval Research Laboratory. The following year, the United States Army successfully tested a primitive surface to surface radar to aim coastal batterysearchlights at night. This design was followed by a pulsed system demonstrated in May 1. Rudolf Khnhold and the firm GEMA in Germany and then another in June 1. Air Ministry team led by Robert A. Watson Watt in Great Britain. A Chain Home tower in Great Baddow, Essex, United Kingdom. In 1. 93. 5, Watson Watt was asked to judge recent reports of a German radio based death ray and turned the request over to Wilkins. Wilkins returned a set of calculations demonstrating the system was basically impossible. When Watson Watt then asked what such a system might do, Wilkins recalled the earlier report about aircraft causing radio interference. This revelation led to the Daventry Experiment of 2. February 1. 93. 5, using a powerful BBC shortwave transmitter as the source and their GPO receiver setup in a field while a bomber flew around the site. When the plane was clearly detected, Hugh Dowding, the Air Member for Supply and Research was very impressed with their systems potential and funds were immediately provided for further operational development. Watson Watts team patented the device in GB5. Development of radar greatly expanded on 1 September 1. Watson Watt became Superintendent of a new establishment under the British Air Ministry, Bawdsey Research Station located in Bawdsey Manor, near Felixstowe, Suffolk.
