BALLISTIC RANGING METHODS AND SYSTEMS FOR INCLINED SHOOTING

摘要

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.
