MULTISPECTRAL SURVEILLANCE-SEARCH SYSTEM FOR REMOTE VIDEO SURVEILLANCE OF OBJECTS Russian patent published in 2025 - IPC H04N7/18 

FIELD: electric communication technique.

SUBSTANCE: invention relates to spectrozonal television and relates to a spectrozonal surveillance system for remote video surveillance of objects. System includes a TV camera, which has a lens, a unit for splitting the input stream into two identical streams, two optical filters and two matrix photodetectors. Outputs of the photodetector arrays are connected to the input of the first and second video signal shaping amplifiers. Signals from the shaping amplifiers are transmitted to the quadrature modulator. Signal generated by the quadrature modulator is transmitted by the radio transmitter over the air communication channel, and on the receiving side there is an antenna with a receiver and a quadrature demodulator. First and second outputs of the quadrature demodulator are connected to the first and second inputs of the unit for calculating and generating m signals of different spectral images. Synchronization signal is transmitted from the receiver to the input of the local generator, the first output of which is connected to the second input of the quadrature demodulator, and its second output is connected to the input of the unit for calculating and generating m signals of different spectral images.

EFFECT: reducing the number of transmitted image signals over a communication channel and enabling generation of signals of different spectral TV images on the receiving side for real-time analysis thereof.
