FIELD: controlling flying vehicles by optical beam from control stations in optical communications and television systems.
SUBSTANCE: proposed method for decoding pulse-width modulated and frequency keyed harmonic-wave signal (guidance command) on board missile used to convert electromagnetic radiation into harmonic signal includes generation of rectangular pulses from harmonic signal filtered off at operating frequency whose amplitude exceeds preset passage threshold, their length being determined by double cutoff angle and separation of constant component from rectangular pulses; in addition harmonic signal converted from electromagnetic radiation is symmetrically limited relative to zero, amplified, and converted into rectangular pulses of duty factor two, then harmonic signal is filtered off from them at operating frequency.
EFFECT: enhanced precision of decoding due to eliminating impact of modulation noise.
