Abstract
A control system for a cannon-launched projectile carrying explosive squibs is shown to comprise: (a) a first control computer, responsive to the range and bearing of a selected ground target, to compute an ideal ballistic trajectory between an artillery piece and such target and to calculate the line of sight between the artillery piece and points on such trajectory; (b) an infrared beam generator and scanner for scanning, under the control of a first clock, such beam in a predetermined pattern centered on the calculated line of sight; (c) a sensor carried on the cannon-launched projectile for detecting when the infrared beam irradiates such projectile; a second clock on the cannon-launched projectile operating synchronously with the first clock to indicate the position of the infrared beam when the cannon-launched projectile is irradiated; and (d), a firing controller for selecting and firing one, or more, explosive squibs to force the cannon-launched projectile toward the ideal ballistic trajectory.
