Passive 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 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 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 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, and in the case of a mobile launching platform li ...

Radar Jamming And Deception
Radar jamming and deception is a form of electronic countermeasures (ECMs) 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 Electronic counter-countermeasur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HN-2000
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 ...

DF-26
The Dong Feng-26 or DF-26 (; NATO reporting name: CH-SS-18) is an intermediate-range ballistic missile deployed by the People's Liberation Army Rocket Force and produced by the China Aerospace Science and Technology Corporation (CASC). Chinese sources claim the DF-26 has a range of over and may conduct precision nuclear or conventional strikes against ground and naval targets. It is China's first conventionally-armed ballistic missile claimed to be capable of reaching Guam and the American military installations located there; this has led to the missile being referred to as the "Guam Express" or "Guam Killer".Wilson: page 4 The possibility that a DF-26 unit could have nuclear warheads makes it likely an adversary would target these missiles in a first strike. This weapon advances military goals from a brinkmanship policy to a calibrated escalation. The missile was officially revealed at the 2015 China Victory Day Parade. In April 2018, it was officially confirmed that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DF-25
DF-25 (Dong Feng-25) was a Chinese two-stage, solid-propellant, road-mobile Intermediate-range ballistic missile (IRBM). Missilethreat.com stated it could deliver a single or multiple conventional warheads weighing over a maximum distance of 3,200 km to 4,000 km. There are conflicting reports on whether the DF-25 entered service, and if so, when. The Federation of American Scientists notes reports that China had abandoned development of the DF-25 in 1996. The U.S. Department of Defense The United States Department of Defense (DoD, USDOD, or DOD) is an executive department of the U.S. federal government charged with coordinating and supervising the six U.S. armed services: the Army, Navy, Marines, Air Force, Space Force, t ... in its 2013 report to Congress on China's military developments made no mention of the DF-25 as a missile in service.

DF-21
The Dongfeng 21 (DF-21; NATO reporting name CSS-5 - Dong-Feng () is a two-stage, solid-fuel, single-warhead medium-range ballistic missile (MRBM) developed by China's Changfeng Mechanics and Electronics Technology Academy. A part of the Dongfeng missile family, the DF-21's development started in the late 1960s, and it was completed around 1985–86, but not deployed until 1991. It was developed from the JL-1 submarine-launched missile, and is China's first solid-fuel land-based missile. The U.S. Department of Defense in 2008 estimated that China had 60-80 missiles and 60 launchers; approximately 10-11 missiles can be built annually. Originally developed as a strategic weapon, the DF-21's later variants were designed for both nuclear and conventional missions. It is thought to be able to carry a high explosive, submunition for tactical/theater-level missions, or a 300 kt nuclear warhead for strategic strikes. The latest variant, the DF-21D, was said to be the world ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mansup
MANSUP are a Brazilian-Emirati family of all-weather, over-the-horizon anti-ship, surface-to-air and land-attack cruise missiles, that evolved into a broad range of weapons from an early-2000s original design of a anti-ship missile that aimed to achieve performance similar to the MBDA MM40 Exocet Block II.Godoy (2012), P. B16 The name ''MANSUP'' stands for "Míssil Antinavio Nacional" in Portuguese. History A mock-up of the Brazilian Navy and Avibras project for an anti-ship missile inspired by the AM39 Exocet was shown in April 2011 during Latin America Aero and Defence (LAAD) exhibition in Rio de Janeiro.

Millimeter Wave Guidance
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 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 environments, and attenuation by rain (rain fade) ...

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] |
Airborne Early Warning And Control
An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial warfare, aerial engagements by informing and directing friendly fighter aircraft, fighter and attack aircraft. AEW&C units are also used to carry out aerial surveillance airborne ground surveillance, over ground and maritime surveillance, maritime targets, and frequently perform battle management command and control (BMC2). When used at altitude, the radar system on AEW&C aircraft allows the operators to detect, track and prioritize targets and identify friendly aircraft from hostile ones in real-time and from much farther away than ground-based radars. Like ground-based radars, AEW&C systems can be detected and targeted by opposing forces, but due to aircraft mobility and extended sensor range, they are much less vul ...

Fighter Aircraft
Fighter aircraft (early on also ''pursuit aircraft'') are military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air supremacy, air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical bombing, tactical and strategic bombing of enemy targets, and helps prevent the enemy from doing the same. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to the target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground-attack aircraft, ground attack and some types, such as fighter-b ...

Datalink
A data link is a means of telecommunications link, 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 (telecommunications), Duplex communications, communications in both directions simultaneously. Aviation In civil aviation, a data-link system (known as Controller Pilot Data Link Communications) is use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
