RESEARCH ON METHODS OF ANALYSIS AND MODELING OF ELECTRONIC WARFARE SOURCES WITH CONSIDERATION OF SPATIAL-FREQUENCY ORIENTATION

The article examines modern approaches to the analysis and modeling of electronic warfare (EW) sources with consideration of spatial-frequency orientation. It is shown that the development of EW systems significantly changes the nature of contemporary armed conflicts, creating conditions under which classical methods of detection and counteraction against jamming signals lose effectiveness. In this context, the use of methods that allow a comprehensive assessment of both frequency and spatial characteristics of electromagnetic emissions becomes particularly relevant. The main directions in the development of spectral, statistical, and spatial analysis methods are analyzed, including high-resolution algorithms (MUSIC, ESPRIT), time-frequency transformation methods, as well as models that account for multipath propagation and dynamic environmental changes. Special attention is given to approaches for modeling EW sources that allow the creation of mathematical and simulation models considering wideband signals, adaptability, and complex signal structures. The results of the study indicate that integrating spatial-frequency analysis with modern signal processing methods and intelligent
