ROTATING MISSILE GUIDANCE WITH CONTROL SURFACE RELAY DRIVE AND SYSTEM TO THIS END Russian patent published in 2009 - IPC F41G7/00 F42B15/01 

FIELD: weapons.

SUBSTANCE: invention relates to development of missile guidance systems (MGS). Proposed method comprises generation of modulates radiation at starting device , reception of radiation by missile and generation of control signals for vertical and horizontal planes. Aforesaid signals are modulated by relay three-position signals C(γ) and S(γ) shifted relative to each other though π/2, aforesaid signals being periodic as to missile bank angle (γ). Linearisation signal is generated, in-phase with aforesaid periodic signals, depending upon n = ω₀/γ where ω₀ is linearisation signal frequency, γ is missile bank rotation frequency. Modulated control signals and linearisation signal are summed to generate relay two-position signal via determining the sign of the above sum and conversion of obtained relay signal into missile control surfaces deflection (MCS). Note here that linearisation signal is generated subject to condition of n=2 or n=4, depending upon MCS delay-γ product.

EFFECT: higher accuracy of guidance.
