METHOD FOR TRANSMITTING CONTROL COMMANDS ON BOARD AERLOGICAL RADIOSONDE AND RADAR SYSTEM IMPLEMENTING IT Russian patent published in 2023 - IPC G01S13/76 G01S13/95 H04B7/26 G01W1/08 

FIELD: radars.

SUBSTANCE: active response radar that can be used in atmospheric radio sounding systems for measuring the slant range from a radar station (radar) to an aerological radiosonde (ARS) using the pulse method and its direction finding along angular coordinates, as well as transmitting telemetric information about the state of the atmosphere to the radar and control commands at the ARS. The claimed method of transmitting control commands to an aerological radiosonde (ARS) with an autodyne asynchronous transceiver includes generation of a command radio pulse in the radar transmitting device, the carrier frequency of which is preliminarily detuned from the frequency of the ARS autodyne generator by an amount at least an order of magnitude greater than the half-width of the synchronization bandwidth autodyne generator, while modulating the carrier frequency of the quasi-harmonic subcarrier, which, in turn, is subjected to additional frequency or phase modulation by a binary code of control commands. The command radio pulse is transmitted via a radio channel to the ARS, where it is mixed with the natural oscillations of the autodyne generator in the resonator of the autodyne generator. The resulting mixture is converted into an autodyne response in the form of changes with the beat frequency in the amplitude and frequency of oscillations, as well as the average value of current and voltage in the bias circuit of the active element. By means of the recording unit, the autodyne response of the generator is isolated in the form of a command radio pulse at the beat frequency with intra-pulse frequency or phase modulation by a binary code of a quasi-harmonic subcarrier. After this, the radio pulse is sequentially amplified in amplitude, filtered with a bandpass filter, converted into a video pulse, and its amplitude is compared with the threshold level. In this case, after filtering the command radio pulse with a beat frequency, its quasi-harmonic subcarrier is demodulated in frequency or phase, thereby obtaining a binary sequence of transmitted control commands, which, provided the amplitude of the video pulse exceeds the threshold level, is converted into a binary parallel code, which is deciphered and divided into channels for transmission to executive devices. A radar system for radio sounding of the atmosphere is also claimed for transmitting control commands to the ARS, which implements the method.

EFFECT: expanded functionality of the atmospheric radio sounding system by creating a channel for transmitting control commands from the radar to the ARS.
