COMBINED MULTI-CHANNEL HOMING HEAD Russian patent published in 2019 - IPC F41G7/00 

FIELD: aviation.

SUBSTANCE: invention relates to aircraft engineering, particularly to optoelectronic homing heads (OHH) used in small-size aviation weapons launched from unmanned aerial vehicles or combat helicopters. Combined multichannel head of self-guidance contains gyro-coordinator, inside external gimbal suspension of which optical unit is installed, which contains interconnected receivers of television (TV) and thermal imaging (TPV) channels and lens, stabilization system of gyroscope axes, video signal processing unit from target. At that, the gyro-coordinator is a gyro-stabilized platform, the gimbal suspension of which is made biaxial, which enables stabilizing the image by heading and pitch using a system for stabilizing the gyro-coordinator axes, for this purpose, stabilization system of gyro-coordinator axes includes interconnected angle sensors, angular velocity sensors, stabilization engines and electronic stabilization board. At that, in optical unit of TV and TPV receivers are located on one optical axis of combined lens, and the electronic image processing board from the target is configured to recognize both stationary targets by comparing their contour and texture features, and small-size targets by analyzing the target feature vector obtained in the optical and infrared ranges, as well as with the possibility of tracking the target with simultaneous tracking of its scale in time.

EFFECT: technical result is increase in accuracy and efficiency of multichannel self-guidance head.
