QRSAM
Quick Reaction Surface-to-Air Missile (QRSAM) is a missile developed by the Defence Research and Development Organisation (DRDO), Bharat Electronics Limited and Bharat Dynamics Limited for the Indian Army, meant for protecting moving armoured columns from aerial attacks. QRSAM has a fully automated Command and Control System. The missile system possesses two four-walled radars both of which encompass a 360-degree coverage, namely, the Active Array Battery Surveillance Radar and the Active Array Battery Multifunction Radar, apart from the launcher while Laser proximity fuze ensures that missile can't be jammed. History As a part of a replacement program for its obsolete Osa-AK and Kvadrat missile systems, Indian Army received a go-ahead to initiate a global acquisition program for quick-reaction surface-to-air missiles from the Ministry of Defence in September 2007. The acquisition program faced multiple issues, including poor response from vendors and re-tendering to avoid sin ...

Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. This evolution of design increasin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

The Pioneer (India)
''The Pioneer'' is an English-language daily newspaper in India. It is published from multiple locations in India, including Delhi. It is the second oldest English-language newspaper in India still in circulation after ''The Times of India''. In 2010, The Pioneer launched its Hindi version in Lucknow. Author Rudyard Kipling (1865-1936), in his early 20s, worked at the newspaper office in Allahabad as an assistant editor from November 1887 to March 1889. In July 1933, ''The Pioneer'' was sold to a syndicate and moved from Allahabad to Lucknow, Uttar Pradesh, at which time the ''Pioneer Mail and India Weekly News'' ceased publication. The newspaper remained a primarily Lucknow-based paper until 1990, when it was purchased by the Thapar Group, under L. M. Thapar, who made it a national newspaper, published from Delhi, Lucknow, Bhubaneswar, Kochi, Bhopal, Chandigarh, Dehradun and Ranchi. Thapar sold the paper to its editor Chandan Mitra in 1998. At that time it had 484 employees. Mi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Radar Jamming And Deception
Radar jamming and deception is a form of electronic countermeasures 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 counter-countermeasures can sometimes he ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Electronic Counter-countermeasure
Electronic counter-countermeasures (ECCM) is a part of electronic warfare which includes a variety of practices which attempt to reduce or eliminate the effect of electronic countermeasures (ECM) on electronic sensors aboard vehicles, ships and aircraft and weapons such as missiles. ECCM is also known as electronic protective measures (EPM), chiefly in Europe. In practice, EPM often means resistance to jamming. A more detailed description defines it as the electronic warfare operations taken by a radar to offset the enemy's countermeasure. History Ever since electronics have been used in battle in an attempt to gain superiority over the enemy, effort has been spent on techniques to reduce the effectiveness of those electronics. More recently, sensors and weapons are being modified to deal with this threat. One of the most common types of ECM is radar jamming or spoofing. This originated with the Royal Air Force's use of what they codenamed ''Window'' during World War II, which ...

Transporter Erector Launcher
A transporter erector launcher (TEL) is a missile vehicle with an integrated tractor unit that can carry, elevate to firing position and launch one or more missiles. History Such vehicles exist for both surface-to-air missiles and surface-to-surface missiles. Early on, such missiles were launched from fixed sites and had to be loaded onto trucks for transport, making them more vulnerable to attack, since once they were spotted by the enemy they could not easily be relocated, and if they were it often took hours or even days to prepare them for launch once they reached their new site. Usually a number of TELs and TELARs are linked to one command post vehicle (CP or CPV). They may use target information from target acquisition, designation and guidance radar (TADAGR or TAR). Transporter erector launcher and radar A transporter erector launcher and radar (TELAR) is a type of TEL that also incorporates part or all of the radar system necessary for firing the surface-to-air missil ...

Air Defence System
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft h ...

Osa-AK
The 9K33 ''Osa'' (, literally "wasp"; NATO reporting name SA-8 ''Gecko'') is a highly mobile, low-altitude, short-range tactical surface-to-air missile system developed in the Soviet Union in the 1960s and fielded in 1972. Its export version name is Romb. Development Design work on an entirely new, self-propelled air defense guided missile system began in 1960 and was assigned to the Moscow-based () research and design institute under lead designer M.M. Kosichkin. The program initially suffered numerous delays and setbacks due to poorly formulated performance and tactical requirements, as this was a pioneering battlefield air defense system with no equivalents in existence at the time, and no doctrinal experience with such a weapon. P.M. Chukadov was assigned project leader in 1965 after a thorough review of the stalled program. The Osa had service acceptance in 1972 after a period of trials. Description The Osa was the first mobile air defense missile system incorporating it ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Proximity Fuze
A proximity fuze (or fuse) is a Fuze (munitions), fuze that detonates an Explosive material, explosive device automatically when the distance to the target becomes smaller than a predetermined value. Proximity fuzes are designed for targets such as planes, missiles, ships at sea, and ground forces. They provide a more sophisticated trigger mechanism than the common contact fuze or timed fuze. It is estimated that it increases the lethality by 5 to 10 times, compared to these other fuzes. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
