Abstract: The electronic warfare system of fighters can provide combat capacities including situation awareness, passive attack, electronic countermeasure and active stealth, significantly increasing survivability and lethality of fighters. To meet the increasingly higher requirements of the new combat capability of fighter electronic warfare systems, the new requirements brought by the rapid improvement of combat object capability, the combat style close to the actual combat and the continually changing combat environment, and the requirements of different carrier platforms and mission systems, the architecture of the electronic warfare system must be carefully designed. The system engineering method is adopted to research on the requirements and technologies based on OV, CV, SV and TV. On the basis of top-level design concepts including agile-algorithm-process, full-domain-integration, rapid and flexible expansibility to meet variety, the architecture design requirements of the electronic warfare system are discussed from the perspectives of full digital processing, integration, extensibility and openness. Furthermore, the core points of the overall design and system solutions deployed for engineering verification are presented. The effectivity and validity of the architecture are proved, paving the way for the next generation fighter electronic system.

Key words: fighter electronic warfare systems, overall design of system architecture, full digital processing, integration, extensibility, openness
