METHOD OF BEAM CONTROL OVER ROLLING MISSILE AND BEAM-CONTROLLED ROLLING MISSILE Russian patent published in 2012 - IPC F42B15/01 F41G7/24 

FIELD: weapons and ammunition.

SUBSTANCE: proposed method comprises launching and moving missile in control field with rudders folded inside airframe in lengthwise grooves, opening radiation receiver and changing rudders in outside position. It includes generation of first and second channel control signals proportional to missile deviations in control field relative to sighting line in horizontal and vertical planes. It includes generation of carrier frequency periodic signals proportional to missile roll sine and cosine. It comprises demodulation of signals proportional to first and second actuator rudders by carrier frequency signals. Smoothing in frequency band Δω and subtracting signals smoothed in first and second channels from appropriate control signals. Besides, it comprises generation of control signals for first and second actuators by modulation of signal difference in first and second control signals by carrier frequency signals and rudder deviation signals in compliance with control signals. Deviations of rudders after missile start is performed inside missile airframe grooves. Extending rudders outside of airframe is executed after time interval τ₃=(0.3…0.5)/Δω counted from the moment of radiation receiver opening.

EFFECT: higher accuracy.
