FIELD: radio-electronic control systems.
SUBSTANCE: invention relates to radio-electronic control systems (RECS) of aircraft and can be used for homing an air-to-air missile to a given type of aircraft with a turbojet engine from their heterogeneous pair under the influence of speed-shifting interference. The method consists in the fact that in the protractor of the radar homing head (RHH) of the rocket, the measurement and estimation of the angular velocity of rotation of the line of sight "rocket-unresolved in terms of angular coordinates and range of a heterogeneous pair of aircraft with turbojet engines" in the horizontal and vertical planes is carried out, using an accelerometer the rocket’s own accelerations in the horizontal and vertical planes are measured, two glider and compression readings of Doppler frequencies are formed in the rocket’s RHH autoselector, a pre-launch target designation of the type of aircraft with a turbojet engine recognized in it is entered into the rocket’s speed autoselector, readings of centroids of glider and compressor Doppler frequency readings are formed , their estimates are formed, the estimate of the Doppler frequency is calculated, the difference between the estimates is calculated, the derivative of the modulus of the difference between the estimates of the glider and compressor centroids of the Doppler frequencies is calculated, which is compared with a threshold value close to zero, then a decision is made on the impact of speed-stealing interference or their absence, in the event of an impact, the calculation of the mismatch parameters in the RECS by the rocket in the horizontal and vertical planes is carried out.
EFFECT: formation of mismatch parameters in the RECS by an air-to-air missile, which make it possible to hom the missile at a given type of aircraft with turbojet engines from their heterogeneous pair under the influence of speed-shifting interference.
