China’s Ludi Tance No 1 (LT-1) dual-satellite radar system, launched in 2022, represents a significant leap in space-based stealth detection technology. This bistatic radar configuration uses one satellite to transmit radar pulses while its companion receives the echo, reducing interference and background clutter to spot low-observable targets like the US F-22 and the upcoming B-21 Raider continuously, regardless of weather or daylight. Developed by Chinese institutions such as the Shanghai Academy of Spaceflight Technology, the LT-1 reportedly suppresses sea and ground clutter, enhancing radar cross-section at optimal bistatic angles between 30 and 130 degrees. This technology may challenge American air superiority, especially in sensitive areas like the Taiwan Strait, by potentially detecting stealth aircraft previously considered invisible from space. China has also expanded its radar satellite constellation and developed complementary ground-based and quantum radar systems to augment its anti-stealth capabilities. However, Western experts remain cautious, noting that simulated success still requires real-world validation to confirm operational effectiveness in complex combat scenarios. The announcement of these breakthroughs was notably reported in October 2025, underscoring China’s growing ambition to counter US aerial dominance through advanced space-based surveillance.
