Abstract : Described is control circuitry for a gun mounted in a vehicle turret that is non-symmetrical relative to the vehicle front and rear ends. The gun can slew across the front and side areas of the vehicle at a minimum elevation of -20 deg, but due to the turret-vehicle orientation the gun is restricted to a minimum elevation of -7 deg while slewing across the vehicle rear end. Should the gun be slewing toward the rear end of the vehicle while tracking a target at a level below the -7 elevation, then anticipating circuitry in the control system will automatically raise the gun to a safe elevation while the gun is passing over the vehicle rear end. The vehicle rear end is hereafter referred to as an avoidance zone. (Author)
