Hongniao Missile
The HN (reported short for Hong Niao, or Hongniao, 红鸟 meaning Red Bird) missiles are a series of turbofan powered Chinese land attack cruise missiles, based on the X-600. Development Although China was satisfied with the performance of its own Changfeng series land attack cruise missile, an inherent problem with this turbojet powered Changfeng (missile) meant that the size and weight of the missile were too large to be carried by aerial platforms in Chinese inventory and the range of the missile was inadequate. A turbofan powered version was needed, but due to the limitation of Chinese R&D and industrial capability of the time, this could not be achieved immediately. As a result, China decided to take a two-step approach, first to have the turbojet powered Changfeng missile meet the immediate need, then complete development on a turbofan powered version like the Tomahawk (missile family) for deployment on aerial platforms while China was building up its industrial infrastru ...

Kh-55
The Kh-55 (, also known as RKV-500; NATO reporting name: AS-15 "Kent") is a Soviet/Russian subsonic air-launched cruise missile, designed by MKB Raduga in the 1970s. It has a range of up to and can carry nuclear warheads. Kh-55 is launched exclusively from bomber aircraft and has spawned a number of conventionally armed variants mainly for tactical use, such as the Kh-65SE and Kh-SD, but only the Kh-555 appears to have been put into service. The Kh-55 was not the basis of the submarine and ground-launched S-10 Granat or RK-55 ''Relief'' (SS-N-21"Sampson" and SSC-X-4"Slingshot") designed by NPO Novator. The RK-55 is very similar to the air-launched Kh-55 (AS-15 "Kent") but the Kh-55 has a drop-down turbofan engine and was designed by MKB Raduga. Development In the late 1960s, the "Ekho" study conducted by the GosNIIAS institute concluded that it would be more effective to deploy many small, subsonic cruise missiles than the much more expensive supersonic missiles then in favo ...

Air-to-surface Missiles
An air-to-surface missile (ASM) or air-to-ground missile (AGM) is a missile designed to be launched from military aircraft at targets on land or sea. There are also unpowered guided glide bombs not considered missiles. The two most common propulsion systems for air-to-surface missiles are rocket motors, usually with shorter range, and slower, longer-range jet engines. Some Soviet Union, Soviet-designed air-to-surface missiles are powered by ramjets, giving them both long range and high speed. Missile guidance, Guidance for air-to-surface missiles is typically via laser guidance, infrared homing, infrared guidance, optical guidance or via satellite guidance signals. The type of guidance depends on the type of target. Ships, for example, may be detected via passive radar or active radar homing, which is less effective against multiple, small, fast-moving land targets. There is some cross-over between air-to-surface missiles and surface-to-surface missiles. For example, there was ...

People's Liberation Army Ground Force
The People's Liberation Army Ground Force (PLAGF), also referred to as the PLA Army, is the army, land-based service branch of the People's Liberation Army (PLA), and also its largest and oldest branch. The PLAGF can trace its lineage from 1927 as the Chinese Red Army; however, it was not officially established until 1948. History In February 1949, the existing large number of armies and divisions were regularized into up to seventy armies of three divisions each. While some, such as the 1st Army (People's Republic of China), 1st Army, survived for over fifty years, a number were quickly amalgamated and disestablished in the early 1950s. It appears that twenty per cent or even more of the seventy new armies were disestablished up to 1953; in 1952 alone, the 3rd Corps (People's Republic of China), 3rd, 4th Corps (People's Republic of China), 4th, 10th Corps (People's Republic of China), 10th, 17th Corps (People's Republic of China), 17th, 18th Corps (People's Republic of C ...

BeiDou Navigation Satellite System
The BeiDou Navigation Satellite System (BDS; ) is a satellite-based radio navigation system owned and operated by the China National Space Administration. It provides geolocation and time information to a BDS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more BDS satellites. It does not require the user to transmit any data and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the BDS positioning information. The current service, BeiDou-3 (third-generation BeiDou), provides full global coverage for timing and navigation, along with Russia's GLONASS, the European Galileo, and the US's GPS. It consists of satellites in three different orbits, including 24 satellites in medium-circle orbits (covering the world), 3 satellites in inclined geosynchronous orbits (covering the Asia-Pacific region), and 3 satellites in geostationary orbits (covering China).

Synthetic Aperture Radar
Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or 3D reconstruction, 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Infrared Imaging
Infrared thermography (IRT), thermal video or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 μm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body Planck's law of black-body radiation, radiation law, thermography makes it possible to see one's environment with or without optical spectrum, visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Active Radar Homing
Active radar homing (ARH) is a missile guidance method in which a missile contains a radar transceiver (in contrast to semi-active radar homing, which uses only a passive radar, receiver) and the electronics necessary for it to find and track its target autonomously. The NATO brevity code for an air-to-air active radar homing missile launch is fox (code word), Fox Three. Advantages There are two major advantages to active radar homing: * As the missile is tracking the target it is going to be much closer to the target than the launching platform during the terminal phase, thus the missile's tracking can be much more accurate and better resistant to electronic countermeasures. Active radar homing missiles have some of the best kill probability, kill probabilities, along with missiles employing track-via-missile guidance. * Because the missile is totally autonomous during the terminal phase, the launch platform does not need to have its radar enabled at all during this phase, an ...

Millimeter Wave
Extremely high frequency (EHF) is the International Telecommunication Union designation for the band of radio frequencies in the electromagnetic spectrum from 30 to 300 gigahertz (GHz). It is in the microwave part of the radio spectrum, between the super high frequency band and the terahertz band. Radio waves in this band have wavelengths from ten to one millimeter, so it is also called the millimeter band and radiation in this band is called millimeter waves, sometimes abbreviated MMW or mmWave. Some define mmWaves as starting at 24 GHz, thus covering the entire 5G NR frequency bands#Frequency Range 2, FR2 band (24.25 to 71 GHz), among others. Compared to lower bands, radio waves in this band have high atmospheric attenuation: they are absorbed by the gases in the atmosphere. Absorption increases with frequency until at the top end of the band the waves are attenuated to zero within a few meters. Absorption by humidity in the atmosphere is significant except in desert environme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Anti-ship Missile
An anti-ship missile (AShM or ASM) is a guided missile that is designed for use against ships and large boats. Most anti-ship missiles are of the sea-skimming variety, and many use a combination of inertial guidance and active radar homing. A large number of other anti-ship missiles use infrared homing to follow the heat that is emitted by a ship; it is also possible for anti-ship missiles to be guided by radio command all the way. Many anti-ship missiles can be launched from a variety of weapons systems including surface warships (also referred to as ship-to-ship missiles), submarines, bombers, fighter planes, patrol planes, helicopters, shore batteries, land vehicles, and, conceivably, even infantrymen firing shoulder-launched missiles. The term surface-to-surface missile (SSM) is used when appropriate. The longer-range anti-ship missiles are often called anti-ship cruise missiles. Several countries are also developing anti-ship ballistic missiles. Etymology Both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
