electronic warfare

This paper presents a comprehensive study of methods for detecting and localizing electronic warfare (EW) sources under complex conditions, which include the influence of intensive intentional jamming, multipath signal propagation, time-varying emission parameters, and dynamic movement of the sources. The relevance of the research is driven by the growing role of EW means in modern armed conflicts and the need to ensure timely detection and neutralization of such threats.

The article presents the concept of a hardware and software system for detecting and neutralizing unmanned aerial vehicles (UAVs) using interceptor drones. The proposed system uses passive radars that combine different physical detection principles, such as acoustic, radio, and optical. The data obtained is combined to accurately determine the target’s coordinates in airspace. Target coordinates are calculated based on geometric models of a sphere and a spheroid, which ensure an error of no more than 0.3%.

Modern approaches to determining the spatial and frequency parameters of electronic warfare (EW) sources, which are crucial for ensuring the efficiency of electronic intelligence, defense, and countermeasures systems, have been studied. A classification of existing methods, covering spatial, frequency, and combined approaches, has been conducted. The features of using antenna systems, phase methods, triangulation, and correlation analysis to determine the spatial characteristics of sources have been considered.
