…n of uncorrelated radar signals, explaining how primary and secondary radar returns can occur at different times, leading to discrepancies in radar tracking of aircraft.

The document analyzes radar data related to the JAL-1628 incident on November 18, 1986, where the pilot reported a UFO sighting. The analysis concludes that the radar returns were normal and did not indicate any unusual targets.

The document discusses the analysis of radar data related to Japan Airlines flight 1628, which experienced uncorrelated radar signals during its flight on November 17, 1986. FAA experts explain the phenomenon of uncorrelated primary and beacon targets and its implications for radar tracking.
