Resumen
The article analyzes the spatial correlation properties of the scalar electromagnetic field of ionospheric and surface wave radio signals and natural radio interference in the decameter range, obtained on the basis of experimental studies. Based on the analysis, a method for spatial compensation of natural radio interference has been developed, which determines the principle of synthesizing the aperture of antenna systems. Estimates of noise immunity for radio engineering detection systems, built on the basis of the developed method, providing increased sensitivity of the RTS at a given antenna orientation and noise immunity of radio reception, are presented.
