Abstract. Digital antenna arrays application in modern radio-electronic means discloses availabilities of non-classical signal processing methods and antenna arrays building principle. Particularly, use of nonlinear signal processing methods and  nonuniformly-filled array can become a basis for perspective radio-electronic systems creation, which are characterized by improved directional properties of antennas, high interference and noise immunity along with their considerable decrease in value. For detailed analysis of radio electronic systems capabilities the expensive natural experiments are required. In this regard, it is more expedient to assess their capabilities by simulation. The simulation modeling method of spatially-randomized decameter range scalar radiointerference field created by digital antenna array in initial preprocessing paths is presented. The method based on statistically dependent realizations of radiointerference field synthesis with the use of achieved experimental data of spatially-correlated radiointerferences characteristics. The method is recommended for the research of characteristics of radio-electronic systems constructed on the basis of digital antenna array with spatially-correlation signals processing.

Key words: digital antenna array, spatially-correlation characteristics, interference immunity, directional properties, simulation modeling, discrete spectrum, conditional Gaussian distribution law, radiointerference.
