Documents / Report
This declassified CIA document, released through The Black Vault, reports on the meetings of the Scientific Advisory Panel on Unidentified Flying Objects, which the Office of Scientific Intelligence convened on January 14 to 18, 1953. It includes a history of the sessions and the panel's informal comments, and it appends the formal report signed by H. P. Robertson and others. The panel found no evidence of a direct threat to national security. It recommended stripping UFOs of their special status and starting a public education program.

It was agreed by the Panel that no government-sponsored program
of optical nation-wide sky patrol is worthwhile at the present time,
and that the encouragement of amateur astronomers to undertake such
a program might have the adverse effect of' over-emphasizing rrflying
sauceru stories in the public mind. However, the issue of radar'scope
cameras for recording peculiar radar echoes would serve peveral pur-
poses, including the better understanding of' radar interference as
well ac ±dentif'ication of U.F.O.'s.
RADAR PROBLm·1 OF .MUTUAL 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 show as a high-speed track
or series of dots was recognized to have probably caused a number of
U.F.o. reports. This problem was underlined by inf'orw~tion received
indicating ADC concern in solving this problem of signal identif'ication
before service use of very high-speed aircraft or guided missiles
25X1A (1955-1956). believed that one answer to this problem 25X1A
~ra.s the uoe of a rrdoppler f'ilter't in the receiving circuit•
suggested that the problem might be better solved by the use of a
ttcontrolled jitter" wherein the operator receiving rrvery fast tracl{S 11
(on the order of 1000 - 10,000 m.p.h.) ~rould operate a circuit iihich
would alter slightly his station's pulse frequency rate. If the signal
received on the screen had been caused by mutual interference vdth
another station, the track would now whow itself at a different distance
