Fourth generation fighters have AI radars that include which types?

• A. Mechanically Scanned Radar, PESA, and AESA
• B. Mechanically Scanned Radar only
• C. No AI radar
• D. PESA and AESA only

Answer: (A)

Fourth generation fighters can rely on a spectrum of radar technologies, from older mechanically scanned systems to modern electronically scanned arrays, all of which can incorporate AI processing to help with detection, tracking, and data fusion. Mechanically scanned radars sweep the beam by physically moving the antenna, which is reliable but slower and more vulnerable to wear. PESA, or passive electronically scanned array, uses a single transmitter feeding a phased array and electronically steers the beam, offering faster scanning without moving parts. AESA, or active electronically scanned array, uses many transmit/receive modules for each element, enabling rapid, flexible beam steering and multiple beams, which is ideal for AI-driven processing and simultaneous tasks. Because AI-capable processing can be integrated with any of these radar types, the correct option includes all three: mechanically scanned, PESA, and AESA. The other choices omit one or more valid radar types or imply no AI capability, which isn’t accurate for fourth generation fighters.
