METHOD OF NOISE AUTOMATIC GAIN CONTROL Russian patent published in 2024 - IPC H03G3/20 

FIELD: radar equipment.

SUBSTANCE: invention relates to radar engineering and can be used in constructing various radar or similar receiving amplification paths. In the noise automatic gain control method, performing the measured levels of noise power and the mixture of the useful signal and noise at the output of the amplification path, calculating and storing the value of the difference between the integrated power levels of the noise and the mixture of the useful signal and noise, a correction signal is generated by determining the sign of the difference between the value of the difference between the integrated power levels of the mixture of the useful signal and noise in the i-th and (i-1)-th cycles, and the threshold level of the threshold device is controlled.

EFFECT: high signal-to-noise ratio at the output of the amplifying path.
