The global UAV radar market is projected to grow from USD 360.7 million in 2026 to USD 990.2 million by 2031 at a 22.4% compound annual growth rate, according to MarketsandMarkets. Demand is being supported by rising procurement of counter-UAS systems, greater radar integration on military UAVs and the need to detect and track small, low-flying and low-observable aerial targets. The market is also shifting toward compact low-SWaP sensors, electronically scanned arrays, software-defined architectures and multisensor systems for intelligence, surveillance and reconnaissance, maritime monitoring, detect-and-avoid, border security and air defense. Hybrid mechanical-electronic scanning radar is projected to record the highest CAGR among scanning types, at 24.2%, while ISR and surveillance radar payloads are expected to hold the largest onboard-radar share in 2026. X-band radar is forecast to account for 26% of the market in 2026, defense users for 50.1%, and large UAVs weighing more than 600 kilograms for the largest share of onboard radar demand. Asia Pacific is projected to post the highest CAGR through 2031. Key companies include RTX, Leonardo S.p.A, Saab AB, HENSOLDT AG and Israel Aerospace Industries.
