Abstract
When radar stations operate, radio pulses of varying intensity are received at the receiver input depending on the type of target, range to the target and other factors. Adjusting the receiver gain is necessary to adjust its sensitivity in such a way as to provide the best reception of signals with amplitudes that vary widely. The article discusses a logarithmic automatic gain control system, analyzes its advantages and disadvantages compared to classical automatic gain control system, and performs its simulation in the graphical programming environment Matlab/Simulink.
