TARGET LOCKING MODULE Russian patent published in 2017 - IPC F41G1/00 

FIELD: weapon and ammunition.

SUBSTANCE: invention can be used as a part of the training portable air defense missile system (PADMS). The target locking module (TLM) contains the lens (6), installed in front of the receiver (7), connected to two digital processing unit (DPU) boards (9, 10), interconnected by means of the fixing screws (3). TLM is made in the dimensions of the portable air defense missile system "refrigerator" (PADMS) and it is the drawing office assembly of the cylinder (1) and the hemisphere (2), connected together by the screw connections. In the cylindrical part (1), having the fixed cover (15) from the outside, the above mentioned lens (6) and receiver (7) are sequentially installed and fixed by means of fastening elements, and in the spherical part (2) two above mentioned DPU boards (9, 10) are attached to the hemisphere outer wide wall from its inner side. The DPU is designed with ability of automatical target extraction in the background conditions by comparison with the automatically generated contrast threshold and the target specified area and the electric locking signal formation, while the target hits the locking area, corresponding to the required space angle of the target retention. The DPU is made with the additional possibility of the target extraction against the interference background according to the form and number of objects in the locking zone and the ability to process signals from both the microbolometric and the television receivers. The drawing office assembly of the cylinder (1) and the hemisphere (2) is designed with the ability to be disconnected. The lens (6) is fixed in the cylindrical part of the module with the help of the sealing ring (5), which together with the protective glass (16) installed in front of the lens, protects the housing pressurized volume from the lens side. The receiver (7) is fixed by means of the holders stoppers (4).

EFFECT: provision of the target locking, interference recognition according to the form and number of objects in the locking zone, extension of the TLM application conditions range, using both the thermal- imaging and the television module.
