RADAR RECEIVER WITH AUTOMATIC GAIN CONTROL Russian patent published in 2014 - IPC G01S7/36 

FIELD: radio engineering, communication.

SUBSTANCE: invention is intended for variable intensity clutter suppression. The radar receiver with automatic gain control comprises M controlled amplifiers, outputs of which are connected to corresponding inputs of an adder, the output of which is connected to the input of a target detection unit, as well as a control voltage generating unit, the input of which is connected to the output of one of the controlled amplifiers, M band-pass filters and a delay line with M taps, wherein inputs of the band-pass filters are connected to the input of the radar receiver, outputs of the band-pass filters are connected to inputs of corresponding controlled amplifiers, the input of the delay line is connected to the output of the control voltage generating unit, and delay line taps are connected to control inputs of corresponding controlled amplifiers.

EFFECT: faster operation and high probability of target signal detection.
