Abstract:

An increase in the number of radio-emitting means and sources of interference leads to a complication of the signal-noise situation at the input of the direction-finder and the occurrence of interference of radio emissions falling into the reception band.

The possibility of separating the interference electromagnetic field into individual radio emissions, through the use of their spatial polarization attributes, based on the use of a concentrated antenna system, has been studied. The solution to the problem is based on the use of a triorthogonal antenna system and consists in expanding the resulting vector of the electric field in a coordinate basis, consistent with the spatial and polarization parameters of the incident radio waves. Radio emissions Models with circular, elliptical and linear polarization for plane electromagnetic waves with an arbitrary direction of propagation have been developed. Procedures are proposed for radio emissions processing in a triorthogonal antenna system, which ensure the selection of various sources signals from their interference mixture.

The developed method allows you to separate the interference mixture of the sum of several radio emissions, using the differences of their spatial and polarization features, using a small-sized concentrated triorthogonal antenna system.
