The article presents a theoretical analysis of spatial-frequency methods for filtering and jamming suppression in electronic warfare countermeasure systems. The main types of electronic jamming and their impact on the operation of modern communication, radar, and navigation systems are considered. The principles of spatial and frequency signal selection, as well as the features of their combined application to enhance jamming resistance, are analyzed. Special attention is given to adaptive spatial-frequency algorithms that provide effective suppression of both narrowband and broadband jamming under conditions of intensive electronic interference. A comparative analysis of spatial-frequency methods with individual spatial and frequency approaches is conducted, highlighting their advantages, limitations, and theoretical efficiency boundaries. Prospective directions for the development of spatial-frequency signal processing in the context of cognitive radio systems and integration with artificial intelligence methods are outlined. The obtained results can be used for further theoretical research and improvement of electronic warfare countermeasure systems.
