摘要： The direction of travel of a shell fired by a gun such as a battle tank depends on the boreline direction of the barrel in the region of the muzzle, and even very small boreline errors can give rise to significant aiming errors at long range. Errors in the boreline direction can often exist in guns having relatively long barrels, as mechanical backlash and slackness in the mounting arrangement, and curvature of the barrel due to thermal stress can shift the position of the muzzle sl ightly from its true position. A solid state optical sensor having a two dimensional image surface is arranged to view the muzzle via the sight (periscope) mirror associated with the optical aiming sight of the gun. The optical sensor is positioned closely adjacent to the optical aiming sight so as to enable all position errors between the aiming sight and the muzzle to be removed. The optical sensor is scanned in a television like raster pattern, and window signals are inserted into selected line scans so that the actual position of the muzzle can be very precisely compared with its required position. Any departures from the required position are compensated by feeding correction signals into the optical aiming sight to shift the gunner's aiming mark accordingly.

摘要： Projectile velocity measurement and communication apparatus comprises a microwave probe fixed to a projectile barrel near a muzzle end. An osciliator, having reference frequency selected for exciting a fundamental electromagnetic mode in the barrel, is connected to the probe through a hybrid mixer configured for extracting, from moving projectile-reflected microwaves, a true Doppler signal having a varying frequency related to projectile barrel velocity. A processor, connected for receiving the Doppler signal, measures, by a clock oscillator, Doppler signal periods (half periods). A data presorter in the processor selects a last "N" number of period measurements before the projectile reaches an interference position relative to the probe, to be fed to a fire control computer interface for determination therein of projectile barrel and muzzle velocities, calibration means being provided to update barrel diameter values used in such determination. An alternative, dual reference fre- , quency variation is described, in which a dual hybrid mixer provides two independent Doppler signals, to eliminate dependency of projectile velocity determinations on barrel diameter. A reference frequency modulator and control means therefor are provided to enable microwave communication of information to the projectile, for example, of projectile target time of flight for fusing purposes. Corresponding methods for projectile velocity measurement and communication are provided.
