AEROLOGICAL RADAR SYSTEM WITH A PROTECTED COMMUNICATION CHANNEL Russian patent published in 2020 - IPC G01W1/08 G01S13/95 

FIELD: radio equipment.

SUBSTANCE: invention can be used in designing new systems of radio sounding of atmosphere with concealed telecommunication transmission channel from board of aerological radiosonde (ARS) to basic ground-based radar station (RS) for tracking ARS. Aerological radar system with a protected communication channel comprises an ARS and a basic radar station for tracking and receiving teleinformation, ARS includes a noise-like transmitter comprising a master oscillator, an M-sequence generator, a meteorological parameters unit, a phase encoder, adder modulo 2, a double balanced mixer, a band-pass filter, an output amplifier and a transmitting antenna, and the ground-based radar station includes a noise-like signal receiver comprising an input amplifier, mixers, heterodynes, intermediate frequency filters, intermediate frequency amplifiers, a three-channel correlator, three-channel M-sequence generator, frequency divider, differential amplifier, generator controlled by voltage, frequency doubler, synchronous generator, phase detector, relative phase detector. In information transmission mode, ARS with basic radar station is connected by radio channel with wide beam pattern. Tracking of ARS basic radar station carries out to determine current ARS coordinates in tracking mode of target with narrow beam pattern.

EFFECT: technical result of invention is high security of transmitted along communication channel information from tracking detection systems, as well as high noise immunity in conditions of natural and deliberate interference.
