Advanced Airborne Sensor
The AN/APS-154 Advanced Airborne Sensor (AAS) is a multifunction radar installed on the P-8 Poseidon maritime patrol aircraft. The radar is built by Raytheon as a follow-on to their AN/APS-149 Littoral Surveillance Radar System (LSRS). The AAS has its roots in the highly classified AN/APS-149 LSRS, which was designed to provide multi-function moving target detection and tracking and high resolution ground mapping at standoff ranges covering land, littoral, and water areas. The radar was deployed on a small number of P-3C Orions, with "game changing" results. Containing a double-sided AESA radar with near 360-degree coverage, it could scan, map, track, and classify targets, and do all of these tasks near simultaneously; it was reportedly sensitive enough to pick up a formation of people moving over open terrain. Building upon the LSRS, the AAS also has a double-sided AESA radar, which contains a moving target indicator (MTI) that can detect, classify, and track targets on land and ...

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 ...

Military Electronics Of The United States
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] |
Aircraft Radars
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air bal ...

Phased Array
In antenna theory, a phased array usually means an electronically scanned array, a computer-controlled array of antennas which creates a beam of radio waves that can be electronically steered to point in different directions without moving the antennas. In a simple array antenna, the radio frequency current from the transmitter is fed to multiple individual antenna elements with the proper phase relationship so that the radio waves from the separate elements combine ( superpose) to form beams, to increase power radiated in desired directions and suppress radiation in undesired directions. In a phased array, the power from the transmitter is fed to the radiating elements through devices called ''phase shifters'', controlled by a computer system, which can alter the phase or signal delay electronically, thus steering the beam of radio waves to a different direction. Since the size of an antenna array must extend many wavelengths to achieve the high gain needed for narrow bea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop Grumman E-8 Joint STARS
The Northrop Grumman E-8 Joint Surveillance Target Attack Radar System (Joint STARS) is a United States Air Force airborne ground surveillance, battle management and command and control aircraft. It tracks ground vehicles and some aircraft, collects imagery, and relays tactical pictures to ground and air theater commanders. The aircraft is operated by both active duty U.S. Air Force and Air National Guard units and also carries specially trained U.S. Army personnel as additional flight crew. Development Joint STARS evolved from separate United States Army and Air Force programs to develop technology to detect, locate and attack enemy armor at ranges beyond the forward area of troops. August 2013. In 1982, the programs were merged and the U.S. Air Force became the lead agent. The concept and sensor technology for the E-8 was developed and tested on the Tacit Blue experimental aircraft. The prime contract was awarded to Grumman Aerospace Corporation in September 1985 for two E- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN/APG-76
The AN/APG-76 radar is a pulse Doppler Ku band multi-mode radar developed and manufactured by Northrop Grumman. AN/APQ-92 The first radar of the radar family AN/APG-76 belongs to is AN/APQ-92, which equipped A-6A. AN/APQ-92 is a search and navigational radar, with function called search radar terrain clearance (SRTC) to generate a synthetic terrain display on the pilot's Vertical Display Indicator (VDI), which is a large cathode ray tube (CRT) display in the center of the pilot's console, right under the gun sight. The display showed vertical terrain development in a 53 degree x 26 degree window about the projected flight path. If the Intruder was heading for a valley between two hills, the pilot would see return generally in the shape of two hills (one on either side of the display), with a curving "V" notch in the center between them. The limitation of SRTC is in its inability to detect smaller artificial features - like cables suspend across a valley. AN/APQ-92 is part of DIA ...

Data Link
A data link is the means of connecting one location to another for the purpose of transmitting and receiving digital information (data communication). It can also refer to a set of electronics assemblies, consisting of a transmitter and a receiver (two pieces of data terminal equipment) and the interconnecting data telecommunication circuit. These are governed by a link protocol enabling digital data to be transferred from a data source to a data sink. Types There are at least three types of basic data-link configurations that can be conceived of and used: * Simplex communications, most commonly meaning all communications in one direction only. * Half-duplex communications, meaning communications in both directions, but not both ways simultaneously. * Duplex communications, communications in both directions simultaneously. Aviation In civil aviation, a data-link system (known as Controller Pilot Data Link Communications) is used to send information between aircraft and air tr ...

GBU-53/B
The GBU-53/B StormBreaker, previously known as the Small Diameter Bomb II, is an American air-launched, precision-guided glide bomb. Development was started in 2006 for a class bomb that can identify and strike mobile targets from standoff distances in all weather conditions. It is integrated on the F-15E Strike Eagle and will be integregated into the F/A-18 Hornet and F-35 Lightning fighters. Its first flight was announced on May 1, 2009. A contract to start low rate initial production was awarded to Raytheon in June 2015. The bomb is developed and manufactured by Raytheon. A Boeing/ Lockheed Martin team attempted to develop it but lost in a U.S. Air Force competition. Boeing won the original competition but the project was on hold for several years due to a corruption scandal involving Darleen Druyun. The competition was reopened in September 2005. Operation The bomb can use GPS/INS to guide itself into the general vicinity of a moving target during the initial search ph ...

AGM-158C LRASM
The AGM-158C LRASM (Long Range Anti-Ship Missile) is a stealthy anti-ship cruise missile developed for the United States Air Force and United States Navy by the Defense Advanced Research Projects Agency (DARPA). The LRASM was intended to pioneer more sophisticated autonomous targeting capabilities than the U.S. Navy's current Harpoon anti-ship missile, which has been in service since 1977. The Navy was authorized by the Pentagon to put the LRASM into limited production as an operational weapon in February 2014 as an urgent capability stop-gap solution to address range and survivability problems with the Harpoon and to prioritize defeating enemy warships, which has been neglected since the end of the Cold War but taken on importance with the modernization of the Chinese People’s Liberation Army Navy. Competitors to Lockheed Martin protested the decision to award them a contract given the circumstances of selection and competition for the missile. The Navy responded by saying ...

AGM-84H/K SLAM-ER
The AGM-84H/K SLAM-ER (Standoff Land Attack Missile-Expanded Response) is an advanced stand off precision-guided, air-launched cruise missile produced by Boeing Defense, Space & Security for the United States Armed Forces and their allies. Developed from the AGM-84E SLAM (Standoff Land Attack Missile, itself developed by Boeing Integrated Defense Systems from the McDonnell Douglas Harpoon antiship missile), the SLAM-ER is capable of attacking land and sea targets medium to long range (over 155 nautical miles/270 km maximum). The SLAM-ER relies on the Global Positioning System (GPS) and infrared imaging for its navigation and control, and it can strike both moving and stationary targets. The SLAM-ER can be remotely controlled while in flight, and it can be redirected to another target after launch if the original target has already been destroyed, or is no longer considered to be dangerous ( command guidance). The SLAM-ER is a very accurate weapon; as of 2009 it had the bes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
