Line-of-sight fire, shooting directly at a visible target on a relatively flat trajectory. The target is in the line of sight of the sighting device and the rifleman's rule applies. Line-of-sight range; Line-of-sight (missile), the straight line between the missile and the target; Radar horizon
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.
The frequency of radio waves used by most radars, in the form of microwaves, propagate in straight lines.This generally limits the detection range of radar systems to objects on their horizon (generally referred to as "line of sight" since the aircraft must be at least theoretically visible to a person at the location and elevation of the radar transmitter) due to the curvature of the Earth.
The radial velocity or line-of-sight velocity of a target with respect to an observer is the rate of change of the vector displacement between the two points. It is formulated as the vector projection of the target-observer relative velocity onto the relative direction or line-of-sight (LOS) connecting the two points.
Beam-riding, also known as Line-Of-Sight Beam Riding (LOSBR), beam guidance or radar beam riding [1] 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.
Either the sight was in fixed alignment with the axis of the bore with ranges marked in the sight, and the gunner laid the range mark on the target. Or during laying the gunner physically set the range to offset the axis of the bore from the axis of the sight by the correct amount and laid using the centre mark in the sight.
If your line is lighter, for instance, that doesn't mean you can ignore other precautions, like masking. “There’s really no actionable information to be gained (from looking at whether your ...
Non-line-of-sight (NLOS) radio propagation occurs outside of the typical line-of-sight (LOS) between the transmitter and receiver, such as in ground reflections. Near-line-of-sight (also NLOS ) conditions refer to partial obstruction by a physical object present in the innermost Fresnel zone .
