DIGITAL DEVICE FOR SUPPRESSION OF NOISES Russian patent published in 2000 - IPC

FIELD: radio engineering. SUBSTANCE: invention refers to suppression devices employed in radio engineering systems to suppress signals ( noises ) coming by side lobes of radiation pattern of antenna. It can be used in other systems which suppress undesired signals. Digital device for suppression of noises received by side lobes of radiation pattern of antenna includes auxiliary antenna, gear for complex mating, first multiplier, first select summer, divider, second multiplier, subtracter, third multiplier, second select summer which output is connected to second input of divider. Signal from auxiliary antenna goes to second inputs of first and second multipliers and signal from gear for complex mating goes to second input of third multiplier, to second auxiliary antenna and to second gear for complex mating. Input of third multiplier is connected to output of second auxiliary antenna and output of divider is connected to input of second gear for complex mating whose output is connected to input of second multiplier. Output of subtracter is output of device for suppression of noises. EFFECT: enhanced efficiency and operational accuracy of proposed device. 2 dwg
