When an electro-optical tracking and ranging system is placed in proximity with the guns being controlled thereby, such as on the turret of a tank, there are a range of azimuth and elevation angles of the gun within which the flame present when the guns are being fired serves to temporarily disrupt the tracking process. Means are provided for sensing and/or anticipating the firing of the gun within the critical fields of azimuth and elevation angles and blanking the electro-optical detector over the interval of the occurrence of the gun flame. This prevents saturation of the detector by the gun flame and the disruption of the circuitry included therein which occurs otherwise.
