PASSIVE HOMING HEAD Russian patent published in 2018 - IPC F42B15/01 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to passive homing heads used to generate high-precision weapon control signals. Passive homing head comprises a series-connected receiving device, first correlator, commutator, electronic device, gyrostabilizer and computing device whose output is connected to the second input of the commutator. Output of the gyrostabilizer is the output of the passive homing head and is connected to the second input of the receiving device. In this case, a second correlator and an interference analyzer are series-connected, the output of which is connected to the third input of the commutator, and the second input is connected to the second output of the first correlator, in addition, the input of the second correlator is connected to the output of the receiving device, and the second output is connected to the fourth input of the commutator.

EFFECT: increased noise immunity of the passive homing head due to the formation of a peripheral gate with a large (at least twice) size of the analysis area and the transition with the interference presence in the main tracking gate to accompany the target to the analysis area of the current image captured by the peripheral tracking gate.
