METHOD FOR FIGHTING AGAINST UNAUTHORISED RADIO SIGNAL SOURCES Russian patent published in 2014 - IPC H04W12/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio equipment and can be used to prevent unauthorised access in satellite communication systems. An input signal is subject to matched filtering in a real time mode, and phantom signal coordinates are determined; for that purpose, a coordinate determination method is chosen; after that, the obtained results are assessed as per a maximum accuracy criterion; then, assessment results are sent to an optimum decision-making subsystem that collects information on phantom signals and assesses efficient operation of matched filtering subsystems and determination of location for fine adjustment of weight coefficients in the corresponding subsystems.

EFFECT: technical result consists in improvement of probable prevention of an unauthorised access in satellite communication systems in a real time mode due to joint use of methods of matched digital filtering and determination of phantom signal coordinates.
