Embodiment Construction

[0086] figure 1 is a schematic diagram illustrating the effect on the trajectory of a projectile along an inclined line along which the projectile is fired, thrown or struck (the "initial line of projection", or in the case of a firearm as the "muzzle line"). For illustrative purposes, figure 1 The angles between the projected curves and the respective lines are significantly exaggerated and not drawn to scale.

[0087] Now refer to figure 1 , a "flat shot" projectile path is a path in which a projectile is at a distance R 0 When a target T at and located approximately at the same geographical height as the launcher's vantage point VP is launched, it moves along the path. The projectile weapon has an initial projection line ("leveling shot muzzle line"), which is not really leveling, but is inclined by an elevation angle α with respect to the leveling line of sight (leveling shot LOS). The level shot sight is approximately horizontal and begins at a height h above the ori...

Abstract

A method for shooting a projectile weapon involves determining the inclination of a line of sight from a vantage point VP to a target T and a line-of-sight range R2 to the target, then predicting a trajectory parameter (such as bullet path BP2) at the line-of-sight range, for a preselected projectile P. Using the trajectory parameter, an equivalent horizontal range EHR2 may then be determined, wherein the equivalent horizontal range EHR2 is the range at which the trajectory parameter would be expected to occur if the projectile P were shot from the vantage point VP toward a theoretical target Tth located in a horizontal plane intersecting the vantage point VP. The equivalent horizontal range may be utilized to compensate for ballistic drop when shooting the projectile weapon. The method may be embodied in a handheld laser rangefinder including a memory for storing ballistic data. Systems for automatic hold over adjustment in a weapon aiming device are also disclosed.

Description

[0001] This case asserts the benefit of US Provisional Application No. 60 / 732,773, filed November 1, 2005, which is hereby incorporated by reference. technical field [0002] The present invention relates to a method and system for compensating for ballistic descent, and to a rangefinder implementing the method. Background technique [0003] External ballistics software is well known and widely used to correctly predict the delivery operation of a ballistic object, including ballistic drop and other ballistic phenomena. Common software packages include Infinity 5 distributed by Sierra Bullets TM , and PRODAS, marketed by Arrow Tech Associates, Inc. TM . Many other ballistic software programs also exist. Ballistic software may contain a database of ballistic coefficients and typical muzzle velocities for various particular cartridges, from which a user may select inputs for the ballistic calculations performed by the software. Ballistic software also typically enables a u...
