List Of Unmanned Aerial Vehicles Of The People's Republic Of China
This is a list of unmanned aerial vehicles (UAVs, or 'drones'), of China. There are further categories and sub-categories following the main, comprehensive list, and some of the UAVs appear in more than one category/ sub-category when they can be classified by more than one. As late of 2010, there are more than a hundred UAV developers/manufacturers currently in China. By 2014, that number is increased to over two hundred thirty UAV developers / manufacturers in China, with over two-thirds of them are private enterprises (PE), and the remaining are government-owned enterprises. Most of the government-owned enterprises are fully capable of indigenously completing the entire development of UAVs of various sizes, from the initial design at the very beginning, all the way to the final completion of UAVs of various sizes, ranging from the smallest micro air vehicle (MAV)s to the largest UAVs. In contrast, most private enterprises lack such capability because they are assemblers purch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synthetic Aperture Radar
Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam-scanning radars. SAR is typically mounted on a moving platform, such as an aircraft or spacecraft, and has its origins in an advanced form of side looking airborne radar (SLAR). The distance the SAR device travels over a target during the period when the target scene is illuminated creates the large ''synthetic'' antenna aperture (the ''size'' of the antenna). Typically, the larger the aperture, the higher the image resolution will be, regardless of whether the aperture is physical (a large antenna) or synthetic (a moving antenna) – this allows SAR to create high-resolution images with comparatively small physical antennas. For a fixed antenna size and orientation, objects which are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing Insitu ScanEagle
The Boeing Insitu ScanEagle is a small, long-endurance, low-altitude unmanned aerial vehicle (UAV) built by Insitu, a subsidiary of Boeing, and is used for reconnaissance. The ScanEagle was designed by Insitu based on the Insitu SeaScan, a commercial UAV that was intended for fish-spotting. The ScanEagle continues to receive improvements through upgrades and changes. Design and development ScanEagle is a descendant of another Insitu UAV, the Insitu SeaScan, which was conceived of as a remote sensor for collecting weather data as well as helping commercial fishermen locate and track schools of tuna. ScanEagle emerged as the result of a strategic alliance between Boeing and Insitu. The resulting technology has been successful as a portable Unmanned Aerial System (UAS) for autonomous surveillance in the battlefield, and has been deployed since August 2004 in the Iraq War. ScanEagle carries a stabilized electro-optical and/or infrared camera on a lightweight inertial stabilized t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Booster (rocketry)
A booster rocket (or engine) is either the first stage of a multistage launch vehicle, or else a shorter-burning rocket used in parallel with longer-burning sustainer rockets to augment the space vehicle's takeoff thrust and payload capability. Boosters are traditionally necessary to launch spacecraft into low Earth orbit (absent a single-stage-to-orbit design), and are especially important for a space vehicle to go beyond Earth orbit. The booster is dropped to fall back to Earth once its fuel is expended, a point known as ''booster engine cut-off'' (BECO). Following booster separation, the rest of the launch vehicle continues flight with its core or upper-stage engines. The booster may be recovered, refurbished and reused, as was the case of the steel casings used for the Space Shuttle Solid Rocket Boosters. Drop-away engines The SM-65 Atlas rocket used three engines, one of which was fixed to the fuel tank, and two of which were mounted on a skirt which dropped away at BECO ...

Egyptian Armed Forces
The Egyptian Armed Forces ( arz, القُوّات المُسَلَّحَة المِصْرِيَّة, alquwwat almusalahat almisria) are the military forces of the Arab Republic of Egypt. They consist of the Egyptian Army, Egyptian Navy, Egyptian Air Force and Egyptian Air Defense Forces. The President of the Republic serves as the Supreme Commander of the Armed Forces. The Minister of Defence and Commander-in-Chief of the Armed Forces, the senior uniformed officer, is Colonel General Mohamed Zaki (since June 2018), and the Chief of Staff is Lieutenant General Osama Askar (since October 2021). Senior members of the military can convene the Supreme Council of the Armed Forces, such as during the course of the Egyptian Revolution of 2011, when President Mubarak resigned and transferred power to this body on February 11, 2011. The armament of the Egyptian armed forces varies between eastern and western sources through weapons deliveries by several countries, led by the United St ...

Electronic Countermeasures
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers. History The first example of electronic countermeasures being applied in a combat situation took place during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Warfare
Electronic warfare (EW) is any action involving the use of the electromagnetic spectrum (EM spectrum) or directed energy to control the spectrum, attack an enemy, or impede enemy assaults. The purpose of electronic warfare is to deny the opponent the advantage of—and ensure friendly unimpeded access to—the EM spectrum. EW can be applied from air, sea, land, and/or space by crewed and uncrewed systems, and can target communication, radar, or other military and civilian assets. The electromagnetic environment Military operations are executed in an information environment increasingly complicated by the electromagnetic spectrum. The electromagnetic spectrum portion of the information environment is referred to as the electromagnetic environment (EME). The recognized need for military forces to have unimpeded access to and use of the electromagnetic environment creates vulnerabilities and opportunities for electronic warfare in support of military operations. Within the informat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moving Target Indication
Moving target indication (MTI) is a mode of operation of a radar to discriminate a target against the clutter. It describes a variety of techniques used for finding moving objects, like an aircraft, and filter out unmoving ones, like hills or trees. It contrasts with the modern stationary target indication (STI) technique, which uses details of the signal to directly determine the mechanical properties of the reflecting objects and thereby find targets whether they are moving or not. Early MTI systems generally used an acoustic delay line to store a single pulse of the received signal for exactly the time between broadcasts (the pulse repetition frequency). This stored pulse will be sent to the display along with the next received pulse. The result was that the signal from any objects that did not move mixed with the stored signal and became muted out. Only signals that changed, because they moved, remained on the display. These were subject to a wide variety of noise effects that m ...

Reconnaissance Aircraft
A reconnaissance aircraft (colloquially, a spy plane) is a military aircraft designed or adapted to perform aerial reconnaissance with roles including collection of imagery intelligence (including using photography), signals intelligence, as well as measurement and signature intelligence. Modern technology has also enabled some aircraft and UAVs to carry out real-time surveillance in addition to general intelligence gathering. Before the development of devices such as radar, military forces relied on reconnaissance aircraft for visual observation and scouting of enemy movement. An example is the PBY Catalina maritime patrol flying boat used by the Allies in World War II: a flight of U.S. Navy Catalinas spotted part of the Japanese fleet approaching Midway Island, beginning the Battle of Midway. History Prior to the 20th century machines for powered and controllable flight were not available to military forces, but some attempts were made to use lighter than air craft ...

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Tr ...
