This Central Intelligence Agency memorandum by F. C. Durant reports on the January 1953 meetings of the Office of Scientific Intelligence Scientific Advisory Panel on Unidentified Flying Objects, chaired by Dr. H. P. Robertson. It covers the history of the sessions and the panel members' comments on individual cases, radar interference, instrumentation and an educational program. The panel concluded unanimously that the sightings showed no direct threat to national security. It recommended training and public education to strip UFOs of their special status.

It was agreed by the Panel that no government-sponsored program of optical nation-wide sky patrol in worthwhile at the present time, and that the encouragement of astronaut astronomers to undertake such a program might have the adverse effect of over-emphasizing "flying saucer" stories in the public mind. However, the issue of radar scopes cameras for recording popular radar echoes would curve several purposes, including the better understanding of radar interference as well as identification of U.T.O.°C. RADAR PROBLEM OF ACTUAL INTERFERENCE This characteristic problem of radar operation wherein the pulse signal (of approximately the same frequency) from station A may be picked up on the screen of station B and chow on a high-speed track as series of data was recognized to have probably caused a number of V.F.O. reports. This problem was underlined by information received indicating ADC concerns in solving this problem of signal identification before service use of very high-speed aircraft or guided minilines (1955-1956). Dr. Perinar believed that one answer to this problem was the use of a "doppler filter" in the receiving circuit. Dr. Alvaros suggested that the problem might be better solved by the use of a "controlled jitter" wherein the operator receiving "very fast tracks" (on the order of 1000-10,000 n.p.h.) would operate a circuit which would alter slightly his station's pulse frequency rate. If the signal received on the screen had been caused by natural interference with another station, the track would now itself at a different distance. Copied From Hearty Illegible Original
