METHOD OF FIRING MISSILES CONTROLLED BY LASER BEAM, AND OPTICAL SIGHT OF MISSILE GUIDANCE SYSTEM Russian patent published in 2016 - IPC F41G7/26 

FIELD: weapons and ammunition.

SUBSTANCE: group of inventions relates to shells guidance systems. Method of firing with shells controlled by a laser beam includes measurement of the range to the target and introduction of the measured value D_T in a ground-based control system, comparison of the measured range to the target D_T with stored in memory of the ground control system range value D_min, allowing introduction of beam axis excess relative to target sighting line, setting of the excess under the condition D_T>D_min, launching of a guided shell, flight of the shell in the beam with an excess above the target sighting line until the moment of time set in the ground-based control system in accordance with the measured range to target, and alignment of the beam axis with the target sighting line. At that, when distance to the target is less than distance D_min, but more than distance D_EG, where D_EG is the range to the shell at time moment $$t_{EG}=\frac{\mathrm{2,5}\dots \mathrm{3,5}}{{\omega }_{coff}};$$ ω_coff is a cutoff frequency of the system of shell control, rad/s, the centre of information field of the beam during the time from shell launch to time moment t_M, where $$t_{М}=\frac{\mathrm{0,5}\dots \mathrm{1,5}}{{\omega }_{coff}},$$ are displaced upward relative to the axis of the beam by the value Y_EG= (0.2…0.5) R_b, where R_b is the radius of the beam, after which they are matched during the time interval from moment of t_M to moment t_EG, while, when the distance to the target is less than distance D_EG, firing is performed without any displacement of the centre of information field of the beam. Proposed device is equipped with electronic displacement generator whose input is connected to the output of the generator of time intervals, and output is connected to the first input of the adder.

EFFECT: technical result consists in ensuring a possibility to exclude a contact of the shell with the underlying surface.
