A target acquisition system for a mobile air defense system is capable of acquiring and engaging targets in rapid sequence while mounted on a moving vehicle. It incorporates a gyrostabilized turret drive system, an optical sight, a forward looking infrared scanner, an infared guided missile subsystem, an onboard computer, and system controls and displays. The turret drive will maintain a particular elevation and azimuth regardless of the motion of the vehicle on which the turret is mounted so that the target tracking system need not account for movement of the vehicle over the ground. The optical sight projects a set of reticles on a combining glass in front of the gunner, which shows the target on which the missile seeker is locked as well as the target at which the turret is pointed so that gunner can insure that the missile is locked on the correct target. Critical systems status signals are also displayed on the sight reticle by use of symbology so the gunner can monitor the key systems without taking his eyes off the target. The missile system controls eight missiles, two being activated at any one time, and notifies the gunner by an audio tone that the missile is locked onto a target and is ready to fire. The missile firing sequence is automatically controlled by the control electronics and inserts super elevation and lead angle automatically, and selects and activates the next missile to be fired without delay.
