METHOD OF GUIDANCE Russian patent published in 1998 - IPC

FIELD: guidance systems with teleorientation of missile by laser beam, antitank missile complexes mounted on land and air carriers. SUBSTANCE: method is result of expansion of usage range of antitank missile complexes fired from mobile carrier without accurate sighting of launcher with reference to target sight line. It is aimed at reduction of requirements for dispersion of missiles at initial phase of guidance. Proposed method of guidance consists in formation of control beam, in formation of control commands proportional to deviation of missile from optical axis of beam, in measurement of angular deviation of missile relative to target sight line, in turn of beam in plane passing through target sight line and missile sight line in direction of flying missile by angle proportional to deviation of missile sight line with regard to target sight line. Proportionality factor is set in range from 0 to 1 by dependence , where h_b is solid angle of control beam; ε_m.max is maximum basic angle between missile sight line and target sight line at initial phase of guidance. EFFECT: expanded usage range of antitank missile complexes, reduced requirements for dispersion of missiles at initial phase of guidance. 1 cl, 2 dwg
