COMPUTER-AIDED COMPENSATOR OF PASSIVE NOISE Russian patent published in 2021 - IPC H04B1/10 G01S13/02 

FIELD: passive interference compensation.

SUBSTANCE: invention relates to the field of passive interference compensation. Disclosed is a passive noise compensator-calculator containing a weight unit, a first delay unit, a first complex adder, a second delay unit, a second complex adder and a sync generator, while the inputs of the first delay unit are connected to the first inputs of the weight unit and the first inputs of the second complex adder, the outputs of the weight the block is connected to the first inputs of the first complex adder, the outputs of which are connected to the inputs of the second delay block, the outputs of which are connected to the second inputs of the second complex adder, the sync generator output is connected to the sync inputs of the weight block, the first delay block, the first complex adder, the second delay unit and the second complex adder, characterized in that the third delay unit, the fourth delay unit and the weight coefficient calculator are introduced, while the inputs of the third delay unit are connected to the first inputs of the weight calculator, the outputs of the third delay unit are connected to the inputs of the first delay unit, the outputs of which are connected to the inputs of the fourth delay unit and the second inputs of the calculator of the weighting coefficient, the output of which is connected to the second input of the weighting unit, the outputs of the fourth delay unit are connected to the second inputs of the first complex adder, the sync generator output is connected to the sync inputs of the third delay unit, the fourth delay unit and the weight coefficient calculator, and the inputs of the passive interference compensator are connected inputs of the third delay unit and the first inputs of the weight coefficient calculator, and the outputs are the outputs of the second complex adder.

EFFECT: increasing the efficiency of compensation for passive interference with a priori unknown correlation properties and separating signals from moving targets.
