Research of the problem of unauthorized access to satellite communications systems

Keywords:

V.E. Kosenko, A.V. Kuzovnikov, R.A. Alekseev


The authors propose a comprehensive approach to struggle unauthorized access in satellite communication systems, which includes two sub-systems: matched filtering and positioning of "parasitic" signals. Both subsystems operate in parallel and complement each other. The results of the two subsystems come in complex analysis, which performs the accumulation of information about the "parasitic" signals and evaluates the effectiveness of the sub-matched filtering and location in order to provide feedback to adjust the weights in the respective subsystems. Thus, considering the totality the implementation of methods unauthorized access causes necessity of development of methods based on a comprehensive approach to the problem. Developed methods for dealing with unauthorized access to combine approaches to detect unauthorized radio signals to determine their parameters, matched filtering and positioning.
