METHOD FOR COMMAND TELECONTROL OF ROCKET Russian patent published in 2006 - IPC F41G7/20 

FIELD: rocketry, applicable in armament complexes of telecontrolled rockets.

SUBSTANCE: the method consists in a rocket launch at an angle to the target sighting line with a subsequent injection into it, measurement of rocket deviation relative to the target sighting line, determination of the evaluations of rocket deviation relative to the target sighting line and the first deviation derivative, formation of the correction signal, computation of the rocket acceleration proportional to the correction signal, and determination of the evaluation of deviation of the rocket and the deviation derivative at an interruption of the process of measurement of deviation with regard to the evaluations of deviation and its first derivative memorized at the moment of interruption of deviation measurement. The novelty in the control method is in the fact that the evaluations of the rocket deviation and of the first derivative of deviation are determined with regard to the evaluation of the second derivative of deviation, the threshold function of the rocket deviation is formed, the difference between the measured rocket deviation and the evaluation of the rocket deviation is determined. The "false-co-ordinate" indication is formed if this difference exceeds the threshold function, the weighting function of the evaluation of the second deviation derivative is formed as a function of the time of absence or the time of the false measurement of the rocket deviation, and at an interruption of the process of measurement of the rocket deviation or in the presence of the "false co-ordinate" indication, the evaluations of deviation of the first and second derivatives of deviation are determined according to the evaluations of deviation memorized at the moment of interruption of the process of measurement and its derivatives with regard to the weighting function of the evaluation of the second derivative of deviation.

EFFECT: enhanced accuracy and performance in terms of error probability.
