Sensor slant range Sensor slant range (1) In radio electronics, especially radar terminology, slant range or slant distance is the distance along the relative direction between two points. If the two points are at the same level (relative to a specific datum), the slant distance equals the horizontal distance.
This means that the rifle sight setting for any range from 0 to 500 meters is available. The sight adjustment procedure can be followed step-by-step. 1. Determine the slant range to the target. Assume that a range finder is available that determines that the target is exactly 300 meters distance. 2. Determine the elevation angle of the target.
Slant Range: Distance along the true line of sight True: Angle in earth coordinates with true north as the reference Relative: Angle in deck-plane coordinates using vehicle heading as the reference Rectangular: Cartesian coordinates typically known as X, Y, and Z Spherical: Polar coordinates typically known as range, bearing, and elevation
Sight distance, in the context of road design, is defined as "the length of roadway ahead visible to the driver".[1] Sight distance is how far a road user (usually a vehicle driver) can see before the line of sight is blocked by a hill crest, or an obstacle on the inside of a horizontal curve or intersection.
Slant range, in telecommunications, the line-of-sight distance between two points which are not at the same level; Slant drilling (or Directional drilling), the practice of drilling non-vertical wells; Slant height, is the distance from any point on the circle to the apex of a right circular cone
Location accuracy is vital to tracking performance because it prevents track corruption when there are multiple targets and makes it possible to determine which road a vehicle is on if it is moving in an area with many roads. The target location accuracy is proportional to the slant range, frequency and aperture length.
Range information is functionally identical to the method provided by civilian DME: pairs of 3.5 microsecond (μs) pulses (measured edge-to-edge at 50% modulation strength) from an aircraft are repeated by the station being interrogated, using the round-trip time to calculate slant-range distance.
The effect is of sufficient magnitude that hunters must adjust their target hold off accordingly in mountainous terrain. A well known formula for slant range adjustment to horizontal range hold off is known as the Rifleman's rule. The Rifleman's rule and the slightly more complex and less well known Improved Rifleman's rule models produce ...
