Abstract:

A target locating and missile guidance system comprising reconnaissance araft equipped with laser or radar range-measuring apparatus in conjunction with a plurality of selectively predetermined ground stations. Range and altitude of the aircraft relative to a detected surface target are obtained at two or more points on its flight path. The positions of the aircraft with respect to the ground stations are simultaneously determined by pulse-time-of-arrival technique. Using triangulation techniques the location of the target is determined with respect to a pulse grid coordinate system associated with the ground stations. At any time after the determination of the location of the target, properly timed signals from the ground stations or command signals based upon time-of-arrival data with respect to pulses from the missile are used to provide accurate guidance of the missile to the target.
