Summary:
- This article discusses a new radar technology developed by Chinese scientists that can track moving targets without emitting any radio signals, making it difficult to detect.
- The radar system uses passive sensing to detect the reflections of existing radio signals, such as those from communication towers or satellites, to locate and track objects like aircraft or ships.
- This technology could have important applications in military and civilian contexts, allowing for stealthy surveillance and monitoring without the risk of being detected by adversaries.
