The study aims to assess the possibilities of integrating air defence radar and electronic warfare (EW) to improve the effectiveness of the air defence system of important facilities. A comprehensive analysis of joint operations of radar air defence assets with electronic warfare assets was conducted, including combat modelling, simulation of real-time data exchange and assessment of the system's adaptability to changing threat conditions. The study demonstrated that the integration of air defence radar with electronic warfare significantly increases the effectiveness of protecting important facilities from air attacks. The analysis shows that the synchronisation of actions between these systems allows for faster detection of air threats and more accurate neutralisation. Real-time electronic warfare assets can effectively interfere with the navigation and control systems of enemy air attack assets, reducing the likelihood of their successful engagement of targets. Modelling of attack scenarios showed that adaptability and rapid exchange of data between systems provide increased flexibility in responding to complex threats. Thus, the integrated use of air defence radar together with electronic warfare significantly improves the overall level of defence systems and increases their resilience to air attacks. The study also determined that the effectiveness of protection is enhanced using automated coordination systems that ensure the rapid exchange of information between detection and electronic warfare systems. In addition, the analysis showed that the use of modern technologies in electronic warfare can significantly reduce the time required to detect and neutralise threats, which is critical for the successful protection of critical facilities.
