CONTROL METHOD OF EQUIPMENT OF AIR DEFENSE ROCKET-CANNON COMPLEX Russian patent published in 2014 - IPC F41G7/20 F41G3/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention refers to control of equipment of air defense rocket-cannon complexes. The control method of equipment of the air defense rocket-cannon complex involves detection and identification of a target, taking of firing decision and calculation of coordinates of a predicted collision point for firing by means of rocket and cannon equipment, guidance of equipment and rocket and/or shell firing, evaluation of firing results and taking decisions on firing continuation. At rocket firing, an aiming mark is aligned with the target by means of a sight; an air flow velocity is measured; angular corrections for deviation both of rocket and cannon equipment from a sighting line are determined considering firing conditions and ballistic characteristics of ejected rockets and shells, availability in the sight field of view of dust and smoke interference and their characteristics; the above corrections are entered to guidance actuators of the corresponding equipment; during flight of the guided rocket and after it is captured with a guidance system, in a number of the trajectory sections there performed is its deviation from the sighting line by correction of control commands of input of an additional constant signal and pseudorandom signals of a random number generator; besides, maximum level of corrected control commands and a deviation value of the rocket from the sighting line are restricted in a perspective plane perpendicular to the sighting line, and when the rocket approaches the target at the specified distance, correction of rocket control commands is stopped.

EFFECT: improving probability of target hitting and reducing probability of hitting of the guided rocket itself.
