Abstract: The system and method of a dual mode semi active laser seeker and imaging system using pulse detection and angle determination as applied to quad detectors to properly identify a correct designator spot. The angle performance is driven by the field of view of the imaging system. The imaging system resolution provides the required angle accuracy for guidance as cued by pulse detection apertures. The imaging system eliminates the need to designate until impact thus eliminating exposure to counter fire against the designator. The elimination of designation until impact also opens up the opportunity rapid engagement of multiple targets from a single designator.
