STAND-ALONE SYSTEM FOR SHIELDING PARABOLIC-REFLECTOR ANTENNA STATIONS AGAINST NOISE SIGNAL AND METHOD FOR ITS CONSTRUCTION Russian patent published in 2007 - IPC H01Q19/19 H01Q15/16 

FIELD: radio-electronic devices.

SUBSTANCE: proposed stand-alone noise-signal system for shielding parabolic-reflector antenna stations against noise signals at known stable directions of their arrival and fixed antenna has passive dissipaters made both of metal and insulation in the form of dissipating straps and mounted on parabolic-reflector internal effective surface; system also has dissipaters for real-time suppression of noise signals moving in space which are made in the form of group or groups of low-directivity antennas forming scattered non-equidistant reflecting phased antenna array of small number of antennas disposed on internal surface of parabolic reflector ; it also has phase shifters, their control unit, processor, and separate power supply, geometry of dissipaters (size, type, quantity of dissipaters, and coordinates of their disposition on effective surface of parabolic reflector surface) being found from respective formulas.

EFFECT: enhanced noise immunity of various radio systems.
