FIELD: radio engineering, communication.
SUBSTANCE: existing interference compensation device further includes series-connected second envelope detector, second adder, as well as a third envelope detector, the input of which is connected to the output of a compensation antenna and the output is connected to the second input of the second adder, the output of which is connected to the second input of a threshold device, and the input of the second envelope detector is connected to the output of the main antenna.
EFFECT: lower probability of false alarm owing to elimination of interference edges.
