The document discusses the phenomenon of uncorrelated radar signals, explaining the differences between primary and secondary radar returns and how they can indicate the presence of an aircraft.

This document discusses the analysis of radar data related to Japan Airlines flight 1628, which encountered 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.

The document discusses the phenomenon of uncorrelated radar signals, specifically detailing the differences between primary radar returns and secondary beacon returns. It includes a diagram illustrating how these signals can appear on a radar screen when they do not match up in time or location.

This memorandum from the Federal Aviation Administration discusses the radar split image phenomenon observed during JAL flight 1628 on November 17, 1986. It acknowledges the interpretation provided by the Alaskan Region Air Traffic Division and includes an analysis of uncorrelated primary and beacon targets.

This document discusses the FAA's analysis of radar data related to Japan Airlines flight 1628, which reported an uncorrelated radar target during its flight on November 17, 1986. The FAA experts explained the phenomenon of uncorrelated primary and beacon targets and its implications for radar tracking.

The document discusses the phenomenon of uncorrelated radar signals, explaining how primary and secondary radar returns can occur at different times, leading to discrepancies in radar tracking of aircraft.

This document provides a detailed analysis of the radar data associated with Japan Airlines flight 1628, which reported an unidentified flying object (UFO) during its flight over Alaska on November 17, 1986. The analysis focuses on the phenomenon of uncorrelated radar signals and the normalcy of the radar returns observed during the incident.

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.

The document discusses the phenomenon of uncorrelated radar signals, explaining the differences between primary and secondary radar returns and their implications for radar tracking of aircraft.

This memorandum from the FAA discusses the radar analysis related to JAL flight 1628, specifically addressing the phenomenon of 'split images' observed during the flight on November 17, 1986.

This document details an incident involving Japan Airlines Flight 1628, which encountered an unidentified aerial phenomenon while flying over Alaska. The flight crew reported seeing a large object with multiple lights and erratic movement, which was tracked by air traffic control.

This document discusses the FAA's analysis of radar data related to Japan Airlines flight 1628, which experienced uncorrelated radar signals during its flight on November 17, 1986. The FAA experts concluded that the radar system detected an 'uncorrelated primary and beacon target', a phenomenon that can occur under certain conditions, particularly when a pil…

This document appears to be a fragmented communication regarding an unidentified aerial phenomenon (UAP) observed by an Air Force pilot. The text is largely illegible and lacks coherent details.

The document appears to be a fragmented and unclear text, possibly related to an unidentified aerial phenomenon or incident. The content is largely illegible and lacks coherent information.

The document discusses the surge of unidentified aerial phenomena reports in the summer of 1947, particularly following Kenneth Arnold's sighting of nine unusual aircraft, which led to the term 'flying saucer' gaining public attention. It speculates on the impact of Arnold's report on subsequent sightings and emphasizes the importance of investigating these …

The document appears to contain fragmented observations of an unidentified aerial phenomenon, detailing its movement and characteristics.
