SYSTEM OF DETECTION OF MOVING OBJECTS BEHIND BARRIER Russian patent published in 2017 - IPC G01S13/04 

FIELD: physics.

SUBSTANCE: invention relates to detection systems and can be used to protect mobile and stationary objects in establishing the penetration of violators into the guarded space and the transmission of alarm signals using near-field radiation based on the use of radar technology and ultra-wideband system technology. It can also be used for search and rescue operations in hard-to-reach areas, in emergency situations (emergencies), incidents, terrorist attacks and in the normal modes of operation of law enforcement agencies and other security agencies. A system of detecting moving objects behind a barrier contains a set of radio wave detection device with a transmitting antenna united by a single radio network and a control center set with a receiving antenna. A set of radio-wave detection devices and a set of control center located outside the protected space are interconnected by a broadband data channel. The set of the radio-wave detection device includes a set of batteries and at least one single wideband detection device (SWDD) configured to emit an ultra-wideband probing signal consisting of a housing in which a power board is connected in series, a radar module with additional amplification stages, a board converter, an interface card, a processor board, a solid state drive, and a transceiver module whose output is connected to a ten-ton for transmitting information to a control center set which includes at least one base station based on a transceiver with an integrated omni-directional antenna and connected to an information processing and display unit (IPDU), analyzing the incoming information, coordinating the work of the SWDD and executed on the basis of a computer. At least one SWDD is arranged with a side of the barrier that is opposite to the guarded space, separating the guarded space from mentioned SWDD, in such a way that the radiated ultra-wideband probe signals cover the entire protected space.

EFFECT: reduction of distortion of the received signal, stable detection of moving objects moving in the vehicle during its movement, under conditions of natural vibrations and impacts, and also in stationary conditions.
