Television guidance (TGM) is a type of missile guidance system using a television camera in the missile or glide bomb that sends its signal back to the launch platform. There, a weapons officer or bomb aimer watches the image on a television screen and sends corrections to the missile, typically over a radio control link.
The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its Probability of Guidance (Pg). [1] These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active", "passive", and "preset" guidance.
Since so many types of missile use this guidance system, they are usually subdivided into four groups: A particular type of command guidance and navigation where the missile is always commanded to lie on the line of sight (LOS) between the tracking unit and the aircraft is known as command to line of sight (CLOS) or three-point guidance.
It can then give electronic instructions to the missile that correct its flight path so it is flying along a straight line from the sighting device to the target. Most antitank SACLOS systems such as Milan and TOW use a strobe or flare ( visible , infrared (IR) or ultraviolet (UV) light) in the tail of the missile with an appropriate sensor on ...
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 ("offboard") source—as it reflects off the target [1] [2] (in contrast to active radar homing, which ...
The SM-6 is the most advanced naval air defence missile in the U.S. arsenal, including against ballistic missiles, and has also been tested for striking ships and ground targets, and in air-to-air ...
Beam riding is one of the simplest methods of missile guidance using a radar. It was widely used for surface-to-air missiles in the post-World War II era for this reason. An early example was the British Brakemine, first tested in 1944, as was the first commercially available SAM, the Oerlikon Contraves RSA.
can someone explain the difference between preset and inertial guidance?-- Arado ( talk ) 12:20, 12 February 2015 (UTC) [ reply ] A torpedo can be preset to travel in a certain direction, or even travel for a certain period and then turn, but if it takes inertial guidance to compensate for unanticipated water currents that could otherwise drag ...
