Line of sight (LoS) propagation from an antenna. Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves can only travel in a direct visual path from the source to the receiver without obstacles. [1] Electromagnetic transmission includes light emissions traveling in a straight line.
[12] [13] Raising the sight line 48.5 to 66 mm (1.9 to 2.6 in) over the bore axis, introduces an inherent parallax problem as the projectile path crosses the horizontal sighting plane twice. The point closest to the gun occurs while the bullet is climbing through the line of sight and is called the near zero.
Line of sight (video games), visibility on a gaming field, i.e. who can see what; Line of Sight (film), a 1960 French drama film; Line of Sight (novel), a techno-thriller novel; Line of Sight: Vietnam, a video game "Line of Sight", a song by Odesza from A Moment Apart; Line-of-sight: Leonardo da Vinci's term for the path that light follows to ...
Direct fire or line-of-sight fire refers to firing of a ranged weapon whose projectile is launched directly at a target within the line-of-sight of the user. [1] The firing weapon must have a sighting device and an unobstructed view to the target, which means no obstacles or friendly units can be between it and the target. A weapon engaged in ...
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.
The MGM-166 LOSAT (Line-of-Sight Anti-Tank) was a United States anti-tank missile system designed by Lockheed Martin (originally Vought) to defeat tanks and other individual targets. Instead of using a high explosive anti-tank (HEAT) warhead like other anti-tank missiles, LOSAT employed a solid steel kinetic energy penetrator to punch through ...
In missile guidance, line of sight (LOS) is the line directly between the launcher/tacker and the target, which must be in view. If the target is moving the missile is constantly manoeuvred to be on the line of sight as it changes, this results in the missile flying a curved path to the target (see command to line-of-sight ).
