SMALL-SIZE ANTI-AIRCRAFT GUIDED MISSILE Russian patent published in 2019 - IPC F42B15/00 

FIELD: rocket equipment.

SUBSTANCE: invention relates to rocketry and can be used in portable anti-aircraft missile systems. Small-size anti-aircraft guided missile comprises roll sensor, steering drive and three-spectral multi-site optical self-guidance head. This head consists of optoelectronic tracking gyro-coordinator with three channels of optical radiation spectrum of division and electronic unit. Electronic unit comprises a programmable logic integrated circuit and a multi-core processor for digital signal processing for implementation of adaptive algorithms for target extraction against background of natural and artificial interferences on the set of amplitude, spectral and trajectory features. Besides, electronic unit comprises analog-digital and digital-to-analogue converter.

EFFECT: high probability of missile hitting the target in conditions of complicated noise-and-target situation and organized optical counteraction, as well as reduction of time losses during sighting and launching of the missile.
