PASSIVE HOMING HEAD Russian patent published in 2021 - IPC F42B15/01 F41G7/22 G05D1/12 

FIELD: military technology.

SUBSTANCE: invention relates to passive homing heads used to generate control signals for high-precision weapons. The passive homing head contains an interference analyzer, a computing device, as well as a receiving device, a first correlator, a switchboard, an electronic device and a gyro stabilizer, the output of which is the output of the passive homing head and is connected to the combined inputs of the receiving device and the computing device, connected in series. The input and output of the interference analyzer are connected to the output of the first correlator and the second input of the switchboard, respectively. Additionally, a series-connected reference image shaper, an image analyzer and a second correlator are introduced, the output of the latter is connected to the third input of the switchboard. The first input of the reference image shaper is connected to the output of the computing device. The second output of the receiving device is connected to the combined second inputs of the reference image shaper and the image analyzer.

EFFECT: to increase in the accuracy of the homing head guidance when exposed to interference, including spatially extended masking, by replacing the real current image with its copy, which dynamically changes in real time in accordance with the change in the parameters of the homing head flight.
