“China’s New Laser Sensor Could Detect an F-35 From 38 Miles Away!”
“China Just Modeled a Laser That Could Track an F-35 at Night!”
Chinese researchers have modeled a new single-photon LiDAR sensor that could theoretically detect an F-35C from about 38.2 miles, or 61.5 kilometers, away at night. The concept uses 1,064-nanometer laser pulses, a compact 100-millimeter optical system, and extremely sensitive photon detection to identify very weak reflections from an aircraft.
During daylight, the modeled detection range drops to about 17.2 miles because stronger background light creates additional optical noise. At shorter range, the simulation also predicts highly precise depth and transverse measurements.
However, this was a computer simulation rather than a real-world F-35 flight test. The system would also face challenges including its narrow laser beam, atmospheric conditions, detector limitations, and the need to know approximately where to look.
In this episode, we explain how China reached the 38-mile figure, why single-photon LiDAR is important, and what this technology could mean for future aircraft sensing.
