DEVICE FOR DETECTION OF SURFACE FACILITIES FOR SELF-SIGHTING AMMUNITION Russian patent published in 2014 - IPC F41G3/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention refers to military equipment. An optic system output is connected to an optic signal divider input, the output in spectrum range of 7-14 mcm and the output in spectrum range of 0.8-1.1 mcm of which are connected to inputs of a two-channel photoreceiving device. The first output of the two-channel photoreceiving device is connected to the first inertia detector and to the input of the first adder, and its second output is connected through an adjustable amplifier to the input of the second inertia detector and to the second input of the first adder. In addition, the device includes an output coincidence circuit and a detection radio channel that includes in-series connected transmitting-receiving antenna, transmitting-receiving microwave module with a modulating voltage generator, band-pass filter, amplitude detector, low-frequency filter, the third inertia detector, the second threshold device and the second comparator unit, the second input of which is connected through the second voltage divider to the output of the low-frequency filter. The output of the second comparator unit is connected to the second input of the output coincidence circuit, the first input of which is connected to the output of the first comparator unit.

EFFECT: improving detection accuracy of a target and interference immunity of the device.
