CONTROLLED MISSILE GUIDANCE SYSTEM Russian patent published in 2021 - IPC F42B15/01 

FIELD: weapons.

SUBSTANCE: invention relates to weapons equipment, in particular, to firing of guided missiles by ground targets. Invention can be used in designing systems of teleorientation of guided projectiles in a laser beam. Guidance system comprises target viewing system and guidance system, which includes laser radiation source, modulator and optical system with variable focal distance. Said system comprises on-board computer. Projectile entered his memory range change function of time for each value of ground air density in range from 1.5 to 1.1 kg/m³ in increments of 0.1 kg/m³, as well as measured for 30 minutes before firing data meteorological information, ground-air temperature and pressure. On-board computer is provided with the possibility of calculating ground-air density on the basis of the entered weather information, selecting from its memory a function of changing the range of the projectile in time corresponding to the calculated density of ground air, and forming an optical system control command. Optical system includes an amplifier, an electric motor and a reducer for movement of its elements in accordance with the selected law of range variation of the projectile. Besides, guidance system comprises alphanumeric keypad for introduction of ground air temperature and pressure values into computer, controller and digital-to-analogue converter.

EFFECT: technical result is higher accuracy of aiming missiles on target by ensuring constant cross-section of aiming beam at current range of guided projectile.
