China's advancements in radar technology have taken a significant leap with the development of the LARID radar system, capable of detecting plasma bubbles over vast distances. Located in Hainan, this radar can identify plasma bubbles up to 9,600km away, with notable detections occurring over the pyramids in Giza and Midway Islands almost simultaneously. These plasma bubbles are phenomena caused by the disappearance of charged particles in the ionosphere. The largest radar detection event took place from November 4-6, 2023. The LARID radar operates in the 8-22MHz frequency band and has seen its effective detection range improve dramatically from 3,000km to 9,600km in less than six months. Chinese scientists have proposed building additional radars for global monitoring, although it is important to note that LARID is not designed to detect military targets. However, similar technologies are utilized by the Chinese military for tracking stealth aircraft [35ddad71].
In addition to the LARID system, China has developed another advanced radar capable of tracking hypersonic missiles. This radar, created by scientists from Tsinghua University, can track 10 incoming hypersonic missiles traveling at Mach 20. The system incorporates lasers to transmit information at the speed of light, achieving an impressive error margin of only 28cm when estimating the distance of missiles traveling at nearly 7km per second. It boasts a detection range of over 600km and can accurately identify false targets. This microwave photonic radar is considered essential for the next generation of fire-control radars and can be integrated into air-defense missiles or aircraft. Successful laboratory tests have confirmed its capabilities in simulating hypersonic target movements [1d9abd25].
