As a strategic location in the South China Sea, Hainan Island is equipped with multiple military radar stations. From the 1990s to the early 2000s, these stations repeatedly recorded unexplained aerial targets—objects with extreme flight performance far exceeding any known human aircraft.

Hainan Island, South China Sea	1990s-2000s	Military Radar / Air Force

According to data collected by the China UFO Research Association, on a certain night in 1994, a radar station in southern Hainan Island suddenly detected a target flying in from the South China Sea at a speed exceeding 5,000 kilometers per hour. This target moved in a “zigzag” pattern on the radar screen, a mode never seen in any known aircraft.

The radar operator initially suspected equipment malfunction, but cross-referencing revealed that multiple radar stations had tracked the same target simultaneously. This confirmed the physical existence of the target, ruling out atmospheric refraction or equipment error.

Another incident in 1998 was even more dramatic. A coastal radar station on Hainan Island reported a “giant” target flying in from the Gulf of Tonkin—the radar signal was so large that the operator initially thought it was a “group of aircraft.” However, visual observation revealed only a single huge circular luminous object in the sky.

Internal Chinese military reports recorded these incidents as “unidentified aerial situations.” Some reports mentioned that when these UFOs appeared, they often caused strong interference with surrounding communication equipment—radios emitted abnormal noise, and some electronic instruments even temporarily malfunctioned.

This phenomenon is known in UFO research circles as the “EM effect” (electromagnetic effect), and many credible global UFO cases have similar descriptions.

In the late 2000s, with the upgrade of Chinese military radar technology, the number of such reports decreased. However, UFO researchers believe this may be because newer radar systems can more accurately filter out anomalous signals, or because defense departments have raised the classification level of these records.
