INTERFERENCE COMPENSATION DEVICE Russian patent published in 2015 - IPC G01S7/36 

FIELD: physics, radio.

SUBSTANCE: invention relates to radar and can be used in radar receivers for protection from interference. The interference compensation device includes, connected in series, an adder, the first input of which is the main input of the device and the output is the output of the device, a detector, a low-pass filter, a sampling-storage unit, the clock input of which is connected to the clock-pulse input of the device, and a comparator, the second input of which is combined with the input of the sampling-storage unit, a first amplitude controller, the input of which is the compensation input of the device, and the output is connected to the second input of the adder, a phase changer, a second amplitude controller, two integrators and two switches. The device also includes a voltage-to-pulse duration converter, a first coincidence circuit, a pulse polarity inverter and a third switch, a pulse generator, a fourth switch, series-connected second coincidence circuit and T flip-flop, the uncomplemented and complemented inputs of which are connected to the control inputs of the third and fourth switches.

EFFECT: faster operation of the device.
