SYSTEM OF PROTECTION OF IMPULSE RADAR STATIONS FROM ACTIVE NOISE INTERFERENCE Russian patent published in 2007 - IPC G01S7/36 

FIELD: the invention refers to radiolocation particularly to the modes of protection impulse radars from active noise interferences with application of automatic equalization arrangements.

SUBSTANCE: considered impulse radar stations which use in quality of an antenna system an antenna array with electronic scanning of a beam that is with electronics scanning of the diagram of the antenna direction having digital phase changers, a beam synthesizer system of the primary receiving channel, a beam synthesizer of compensating receiving channels and a multi channel automatic compensator which may be realized either by a hardware or by a program mode. Impulse radars' protection system from active noise interferences has an antenna array, digital phase changers, a beam synthesizer of the primary channel, a beam synthesizer of compensating receiving channels, a calculator realizing genetic or any other algorithm of zero phase synthesis, and a multi channel automatic compensator. At that the first output of the antenna array is connected to digital phase changers, and it's second output - with a beam synthesizer of compensating receiving channels, the output of the digital phase changers is connected with the input of the beam synthesizer of the primary receiving channel, whose output is connected with the input of the calculator and the first input of the multi channel of the automatic compensator, the output of the calculator is connected with the second input of the phase changers, and the output of the beam synthesizer of the compensating receiving channels is connected with the second input of the multi channel auto compensator, whose output is the output of the whole impulse radars' protection system.

EFFECT: increases coefficient of suppression of active noise interferences in impulse radars with multi channel automatic compensators.
