METHOD FOR GUIDANCE OF SPIN-STABILIZED MISSILE Russian patent published in 2006 - IPC F41G7/24 

FIELD: development of guidance systems of missiles, applicable in anti-tank and anti-aircraft missile complexes.

SUBSTANCE: the method consists in provision of asymmetric gain factors in the control channels, whose values are determined by the value of compensated phase coupling. The positive effect is attained due to the fact that as compared with the known method consisting in formation of radiation, reception of this radiation by the missile control equipment, formation of signals proportional to the mismatch between the missile and the beam axis in the vertical and horizontal planes, conditioning of the mismatch signals to the signals in the co-ordinate system coupled to the spin-stabilized missile and conditioning of the obtained control signals to the deflection of the control surfaces, the signal proportional to the mismatch between the missile and the beam axis in the vertical plane is amplified with one gain factor, while the signal proportional to the mismatch between the missile and the beam axis in the horizontal plane is attenuated with another factor, which are defined according to mathematical dependences.

EFFECT: enhanced accuracy of fire of rolling missiles in the conditions of varying phase coupling in the guidance system by the value and sign in the process of flight.
