METHOD OF GUIDANCE ROLLING MISSILE AND GUIDANCE SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC F41G7/00 

FIELD: instrument.

SUBSTANCE: error signal containing information about the missile deviation and interference, is additionally summed with the error signal shifted with respect to the source in the direction of delay for a time equal to half the period of the harmonic signal of interference. At that, adjustment of the delay time is inversely proportional to the frequency of rotation about the roll axis, provides interference suppression of variable frequency changing during the missile flight. The guidance system of the rolling missile additionally comprises serially connected clamped amplifier, the second link with adjustable delay time and the second summing amplifier, which output is connected to the second input of the modulator, the second input is connected to the output of the first summing amplifier, connected with the output to the second input of the second link with adjustable time delay. The clamped amplifier input is connected to an output of the period meter.

EFFECT: increase in accuracy of missile guidance in the presence of interference in signals of coordinates at double rotation rate about the roll axis of the missile.
