Abstract:
A method for simulating a shot fired from a gun for ballistic projectiles at a target, preferably an earthbound, moving or standing target, comprising: aiming a sight, whose line of sight extends parallel to a bore axis of the gun, at a target with a setting of a horizontal course (lead) and a vertical course (elevation) of the line of sight from the target; and then manually activating a trigger on the gun to initiate a simulated firing of the gun by the following steps:a) transmitting a first laser beam including a plurality of laser pulses; b) calculating a trajectory of a projectilefictively fired by the gun c) continuously determining deviations of the trajectory from the instantaneous line-of-sight orientation at the firing time; d) pivoting the first laser beam by pivot-angle values that correspond to the trajectory deviations; e) measuring a transit time of the laser pulses that are reflected by the target and f) using in the transit time to determine the target range (r); g1) either comparing the time that has passed between the firing time and the reception of the reflected laser pulses to the flight time of the fictively fired projectile calculated for the target range (r), or g2) comparing actual pivot-angle values of the first laser beam relative to the instantaneous line-of-sight orientation at the firing time, with the actual pivot-angle values being associated with the target range (r), to the theoretical pivot-angle values of the first laser beam relative to the instantaneous line-of-sight orientation at the firing time, with the theoretical pivot-angle values having been calculated from the trajectory data for the target range (r); h) if the compared values match within a tolerance range, transmitting a second laser beam comprising encoded laser pulses is transmitted in the transmission direction last traversed by the first laser beam, with the encoding of the second laser beam containing information about firing data of the gun, including the type of ammunition and weapon, and the identity of the gunner; i) and at the target, when the second laser beam is received by at least one detector disposed on the surface of the target, calculating impact damage from the position of the receiving detector on the target.
