ACTIVE HOMING HEAD Russian patent published in 2019 - IPC F41G7/22 

FIELD: aviation.

SUBSTANCE: invention relates to active homing heads and can be used as an onboard element of aircrafts as a means of guidance for air targets. Active homing head comprises housing 1, on outer surface of which there are vanes with sensor 8 of their angular position. Inside housing 1 there installed is radiation sources 10 10.1 and optical system 2 of lenses with band-pass optical filter 3. Filter 3 is installed after the optical system of 2 lenses before the photodetector. Photodetector is in the form of grid 9 of photodetectors 9.1 installed in front of the front focal plane of optical system 2. Sources 10.1 are made with decrimination, that is, they have extended beam pattern. Outputs of photodetectors 9.1 are connected to board 11 of analogue signal processing. Board 11 comprises in-series connected operational amplifier unit 11.1 and unit of peak detectors 11.2. Outputs of peak detectors 11.2 are connected to board 12 of digital signal processing. Digital signal processing board 12 comprises a multichannel analogue-to-digital converter 12.1, comparator 12.2 and an electronic computer (PC) 12.3. Second signal inputs of computer 12.3 are connected to sensor sensors 8 of the angular position of the foot of the vane, and the control output of computer 12.3 is connected through generator 13 of high-current pulses to the inputs of unit 10 of radiation sources 10.1. Unit 10 of pulse sources contains at least one pulse source 10.1 of target illumination, and grid 9 - not less than three photodetectors 9.1. Signal processing computer 12.3 is based on an ARM (Advanced RISC Machine) architecture with a mathematical coprocessor on a common chip. Signal output of computer 12.3 is connected to output bus of self-guidance head.

EFFECT: technical result is higher reliability of self-guidance head operation.
