  2. Slant range - Wikipedia

    en.wikipedia.org/wiki/Slant_range

    Slant range. 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. An example of slant range is the distance to an aircraft flying ...

  3. Rifleman's rule - Wikipedia

    en.wikipedia.org/wiki/Rifleman's_rule

    Rifleman's rule. Figure 1: Illustration of the Shooting Scenario. Rifleman's rule is a "rule of thumb" that allows a rifleman to accurately fire a rifle that has been calibrated for horizontal targets at uphill or downhill targets. The rule says that only the horizontal range should be considered when adjusting a sight or performing hold-over ...

  4. Distance measuring equipment - Wikipedia

    en.wikipedia.org/wiki/Distance_measuring_equipment

    Distance measuring equipment. In aviation, distance measuring equipment (DME) is a radio navigation technology that measures the slant range (distance) between an aircraft and a ground station by timing the propagation delay of radio signals in the frequency band between 960 and 1215 megahertz (MHz). Line-of-visibility between the aircraft and ...

  5. Tactical air navigation system - Wikipedia

    en.wikipedia.org/wiki/Tactical_air_navigation_system

    A tactical air navigation system, commonly referred to by the acronym TACAN, is a navigation system initially designed for naval aircraft to acquire moving landing platforms (i.e., ships) and later expanded for use by other military aircraft. It provides the user with bearing and distance (slant-range or hypotenuse) to a ground or ship-borne ...

  6. Synthetic-aperture radar - Wikipedia

    en.wikipedia.org/wiki/Synthetic-aperture_radar

    Calculations for the "slant range" (range between the antenna's phase center and the point on the ground) are done for every azimuth time using coordinate transformations. Azimuth Compression is done after the previous step. Step 5 and 6 are repeated for every pixel, to cover every pixel, and conduct the procedure on every sub-aperture.

  7. Shock factor - Wikipedia

    en.wikipedia.org/wiki/Shock_factor

    Shock factor is a commonly used figure of merit for estimating the amount of shock experienced by a naval target from an underwater explosion as a function of explosive charge weight, slant range, and depression angle (between vessel and charge). [1] R is the slant range in feet. W is the equivalent TNT charge weight in pounds = charge weight ...

  8. Trilateration - Wikipedia

    en.wikipedia.org/wiki/Trilateration

    Trilateration is the use of distances (or "ranges") for determining the unknown position coordinates of a point of interest, often around Earth (geopositioning). [1] When more than three distances are involved, it may be called multilateration, for emphasis. The distances or ranges might be ordinary Euclidean distances (slant ranges) or ...

  9. Buffon's needle problem - Wikipedia

    en.wikipedia.org/wiki/Buffon's_needle_problem

    Buffon's needle was the earliest problem in geometric probability to be solved; [2] it can be solved using integral geometry. The solution for the sought probability p, in the case where the needle length l is not greater than the width t of the strips, is. This can be used to design a Monte Carlo method for approximating the number π ...
