Chinese researchers claim that SpaceX Starlink satellite signals could track US stealth fighters, citing their ability to detect a commercial drone’s location using electromagnetic disturbances. The academics, led by professor Yi Jianxin, used a commercial drone to simulate an F-22’s radar signature. They suggest potential military applications but also acknowledge limitations in precision and feasibility.
Based on the meeting notes, the Chinese state-sanctioned study suggests that signals from SpaceX Starlink broadband internet satellites could potentially be used to track US stealth fighters such as the F-22. However, the potential military utility of this capability is disputed and even if it were effective, it is unlikely that Beijing would publicly acknowledge it. The study details how disturbances in electromagnetic signals from Starlink satellites caused by passing aircraft could be used to detect small and stealth targets, such as a commercial drone. The academics specifically tested this using a DJI Phantom 4 Pro drone, which they estimated to have a similar radar signature as a modern F-22 fighter. The research was overseen by the Chinese government’s State Radio Monitoring Centre. The researchers claim that this passive radar system using Starlink satellites could provide significant advantages in detecting such small and stealth targets and suggested potential further military applications. However, the limitations and effectiveness of the system for military use are still in question. It is noted that this technology is not entirely new, but the use of Starlink satellites to spot a target is a novel component. The Chinese academics highlighted the potential advantages of using low-orbit satellite signals combined with covert forward scatter radars. It is mentioned that the feasibility and effectiveness for military use are subject to further research. The study’s findings and the release of this information by China may also serve to instigate skepticism and possibly create a sense of mischief.
