RADAR SYSTEM FOR SOUNDING THE ATMOSPHERE WITH A PHASE-MODULATED TELEMETRY CHANNEL Russian patent published in 2023 - IPC G01S13/95 H04L27/18 

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering, more precisely to radar, and can be used in the development of new systems for radiosounding (SR) of the atmosphere with increased noise immunity for transmitting telemetric information from an aerological probe (ARP) to a ground-based tracking radar station. The radar system for sounding the atmosphere with a phase-modulated telemetry channel contains an aerological radio probe and a ground-based tracking radar station. The atmospheric meteorological information received by the aerological radio probe through the block of primary converters and through the block of coupling of analog and digital information is transmitted to the phase modulator of the superior frequency by a telemetric signal in a microcontroller, to which the generator of the superior frequency is also connected. The output of the phase modulator as part of the microcontroller is connected to the self-displacement circuit of the microwave self-oscillator and further to the microwave self-oscillator of the super-regenerative transceiver, the input/output of which is loaded onto the receiving and transmitting antenna of the aerological radio probe. The ground-based radar tracking station of the aerological radio probe contains a transceiver, an amplifier and a digital receiver, a secondary processing unit for telemetric information and the issuance of meteorological parameters and a microcontroller, which includes a unit for control and calculation of the coordinates of the aerological radio probe, a digital demodulator and software for decoding the telemetric signal. The output of the transceiver is connected to the demodulator of the microcontroller by a data bus via an amplifier and a digital receiver. The unit for control and calculation of the coordinates of the aerological radio probe is connected to the software for decoding the telemetry signal and to the digital demodulator of the microcontroller, from which data is sent to the secondary unit for processing telemetry information and the issuance of meteorological parameters to consumers. The receiving and transmitting antenna of the radar station is connected via a radio channel to the receiving and transmitting antenna of the aerological radio probe.

EFFECT: improving the quality of transmission of the telemetry signal from the ARP, increasing the signal-to-noise ratio in the telemetry channel of the radar receiver, the reliability of receiving telemetry information from the ARP in conditions of natural and artificial interference.
