Beam-riding
Beam-riding, also known as Line-Of-Sight Beam Riding (LOSBR), beam guidance or radar beam riding is a technique of directing a missile to its target by means of radar or a laser beam. The name refers to the way the missile flies down the guidance beam, which is aimed at the target. It is one of the simplest guidance systems and was widely used on early missile systems, however it had a number of disadvantages for long-range targeting and is now found typically only in short-range roles. Basic concept Beam riding is based on a signal that is pointed towards the target. The signal does not have to be powerful, as it is not necessary to use it for tracking as well. The main use of this kind of system is to destroy airplanes or tanks. First, an aiming station (possibly mounted on a vehicle) in the launching area directs a narrow radar or laser beam at the enemy aircraft or tank. Then, the missile is launched and at some point after launch is “gathered” by the radar or laser beam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RIM-2 Terrier
The Convair RIM-2 Terrier was a two-stage medium-range naval surface-to-air missile (SAM), among the earliest SAMs to equip United States Navy ships. It underwent significant upgrades while in service, starting with beam-riding guidance with a range at a speed of Mach 1.8 and ending as a semi-active radar homing (SARH) system with a range of at speeds as high as Mach 3. It was replaced in service by the RIM-67 Standard ER (SM-1ER). Terrier has also been used as the base stage for a family of sounding rockets, beginning with the Terrier Malemute. History The Terrier was a development of the Bumblebee Project, the United States Navy's effort to develop a surface-to-air missile to provide a middle layer of defense against air attack (between carrier fighters and antiaircraft guns). It was test launched from on January 28, 1953, and first deployed operationally on the s, and , in the mid-1950s, with ''Canberra'' being the first to achieve operational status on Ju ...

Missile Guidance
Missile guidance refers to a variety of methods of guiding a missile or a guided bomb to its intended target. The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its Probability of Guidance (Pg). These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active", "passive", and "preset" guidance. Missiles and guided bombs generally use similar types of guidance system, the difference between the two being that missiles are powered by an onboard engine, whereas guided bombs rely on the speed and height of the launch aircraft for propulsion. History The concept of unmanned guidance originated at least as early as World War I, with the idea of remotely guiding an airplane bomb onto a target, such as the systems developed for the R.F.C. World War I Drone Weapons, first powered drones by Archibald Low (the father of radio guidance). In World War ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Starstreak (missile)
Starstreak is a British short-range surface-to-air missile that can be used as a man-portable air-defence system (MANPADS) or used in heavier systems. It is manufactured by Thales Air Defence (formerly Shorts Missile Systems) in Belfast, Northern Ireland. It is also known as Starstreak HVM (High Velocity Missile). After launch, the missile accelerates to more than Mach 4, making it the fastest short-range surface-to-air missile in existence. It then launches three laser Beam riding, beam-riding submunitions, increasing the likelihood of a successful hit on the target. Starstreak has been in service with the British Army since 1997. In 2012 Thales relaunched the system as ForceSHIELD. Development Development on the missile began in the early 1980s after an evaluation of missile and gun options to increase air defence capabilities showed that a high-velocity missile system would best meet the needs and could also replace existing shoulder-launched missiles.

Air Defense Anti-Tank System
The Oerlikon/Martin Marietta air defense anti-tank system (US designation MIM-146 ADATS) is a dual-purpose short range surface-to-air and anti-tank missile system based on the M113A2 vehicle. The ADATS missile is a laser-guided supersonic missile with a range of 10 kilometers (6.2 miles), with an electro-optical sensor with TV and forward looking infrared (FLIR). The carrying vehicle also has a search radar with an effective range of over 25 kilometers (16 miles). The first firing of an ADATS missile occurred in June 1981. Canada was the launch customer for the system with 36 units on the M113 chassis ordered for the Canadian Army in 1986. The system was further developed and produced at a new facility in Québec. The US Army also selected ADATS installed on the M2 Bradley chassis but by the time it was ready for service the ending of the Cold War led the US Army to cancel its orders, after Oerlikon invested over CHF 1 billion in the project. A small number of vehicles, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Command Guidance
Command guidance is a type of missile guidance in which a ground station or aircraft relay signals to a guided missile via radio control or through a wire connecting the missile to the launcher and tell the missile where to steer to intercept its target. This control may also command the missile to detonate, even if the missile has a fuze. Typically, the system giving the guidance commands is tracking both the target and the missile or missiles via radar. It determines the positions and velocities of a target and a missile, and calculates whether their paths will intersect. If not, the guidance system will relay commands to a missile, telling it to move the fins in a way that steers in the direction needed to maneuver to an intercept course with the target. If the target maneuvers, the guidance system can sense this and update the missiles' course continuously to counteract such maneuvering. If the missile passes close to the target, either its own proximity or contact fuze wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aperture
In optics, the aperture of an optical system (including a system consisting of a single lens) is the hole or opening that primarily limits light propagated through the system. More specifically, the entrance pupil as the front side image of the aperture and focal length of an optical system determine the cone angle of a bundle of rays that comes to a focus in the image plane. An optical system typically has many structures that limit ray bundles (ray bundles are also known as ''pencils'' of light). These structures may be the edge of a lens or mirror, or a ring or other fixture that holds an optical element in place or may be a special element such as a diaphragm placed in the optical path to limit the light admitted by the system. In general, these structures are called stops, and the aperture stop is the stop that primarily determines the cone of rays that an optical system accepts (see entrance pupil). As a result, it also determines the ray cone angle and brightne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-active Radar Homing
Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal—provided by an external source via radar illumination—as it reflects off the target (in contrast to active radar homing, which uses an active radar transceiver). Semi-active missile systems use bistatic continuous-wave radar. The NATO brevity code for a semi-active radar homing missile launch is Fox One. Concept The basic concept of SARH is that since almost all detection and tracking systems consist of a radar system, duplicating this hardware on the missile itself is redundant. The weight of a transmitter reduces the range of any flying object, so passive systems have greater reach. In addition, the resolution of a radar is strongly related to the physical size of the antenna, and in the small nose cone ...

Anti-tank Guided Missile
An anti-tank guided missile (ATGM), anti-tank missile, anti-tank guided weapon (ATGW) or anti-armor guided weapon is a guided missile primarily designed to hit and destroy heavily armored military vehicles. ATGMs range in size from shoulder-launched weapons, which can be transported by a single soldier, to larger tripod-mounted weapons, which require a squad or team to transport and fire, to vehicle and aircraft mounted missile systems. Earlier man-portable anti-tank weapons, like anti-tank rifles and magnetic anti-tank mines, generally had very short range, sometimes on the order of metres or tens of metres. Rocket-propelled high-explosive anti-tank (HEAT) systems appeared in World War II and extended range to the order of hundreds of metres, but accuracy was low and hitting targets at these ranges was largely a matter of luck. It was the combination of rocket propulsion and remote wire guidance that made the ATGM much more effective than these earlier weapons, and ga ...

9M119 Svir
The 9K120 ''Svir'', 9K119 ''Refleks'', 9K119M ''Refleks-M'' (NATO reporting name AT-11 ''Sniper'') are laser beam riding, guided anti-tank missile systems developed in the Soviet Union. Both are designed to be fired from smoothbore 125 mm tank and anti-tank guns (2A45, 2A46 and 2A46M). The name ''Svir'' comes from the River Svir, while ''Refleks'' means reflex. History The first guided anti-tank missile system fired from smoothbore 125 mm tank guns, the 9K112 Kobra, appeared on Soviet T-64B tanks in 1976. However, they were incompatible with the autoloader of the T-72 tanks (while the T-64 also had an autoloader, it was very different from the one in T-72), so the new missile system was developed for T-72. 9K120 Svir The ''Svir'' is used with the T-72B tank series since 1985. 9K119 Refleks The ''Refleks'' appeared in 1992 and was installed in T-90 tank series. It has also been produced by the People's Republic of China for use with its Type 99 tank. The Indian defen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
