DEVICE FOR FORMATION OF SPIN-STABILIZED MISSILE CONTROL SIGNALS Russian patent published in 2003 - IPC

FIELD: missile control systems, applicable in antitank guided missile and antiaircraft guided missile complexes. SUBSTANCE: the invention consists in formation of the missile control signal proportional to the deflection of the missile from the beam axis and the derivative of this deflection, and providing for reduction of the sensitivity of the control system to radio-frequency interferences on the whole and absence of "emphasizing" of interferences at a doubled roll frequency. The device has a conditioner of the error signal between the missile and the beam axis, and a modulator, whose second input is connected to the output of the transducer of the signal periodic in roll angle, use is made of a series- connected element with an adjustable response time and a summing amplifier, whose output is connected to the first input of the modulator, and the second input of the summing amplifier and the first input of the element with an adjustable response time are connected to the output of the error signal conditioner, as well as a period meter, whose input is connected to the output of the transducer of the signal periodic in roll angle, and the output is connected to the second input of the response element with the aid of which the response time is adjusted. Adjustment of the value of the response time in accordance with the variation of the missile roll frequency in addition to the reduction of the sensitivity to interferences provides for correction of error signals in accordance with variation of the rocket characteristics. EFFECT: enhanced accuracy of guidance of rolling missiles in the presence of radio- frequency noises and interferences. 3 dwg
