support anomalous propagation.
2. Anomalous propagation occurs when the radiated radar beam is bent,
by reflection or refraction, ground. 'he echoes return to the radar
by the same path. The rada ground o some object on the
ground as a target. An apparent mc ving target is observed if the beam
illuminates a moving object or e when the beam illuminates a stationary
object on the ground if the reflecting portion of the atmosphere is itself
in motion. It has been reported that at a range of 50 miles a horizontal
reflecting layer rising 3 meters per second could cause an apparent echo to
move at 300 miles per hour. This appears to be the only likely technical
evnlane
causes. It is possi spurious ignals from ai: orne, shipborne or
ground-based source entally intentionally caus appearance of
the seemingly nonexi targets. wever, as pointed ou in Det 4, FTD
letter (U) "Supplemen UFO Report," May l965, it is unlikely that two
radars operating at different frequencies would observe a false target,
electronically generated, in the same position. Consideration of the avail-
able evidence, however, tends to SUDDort anomalous propagation as the cause.

1. (U) Reference 39IDc letter, "UFo Report," dated 19 9April, forwarded
to FTD by Hq F (5FICO), pertaining to UFO observed 10-11 April 65 on
GCA radar at Misawa AB. Following supplementary information obtained
from Capt. Lester D. Waymire, 1953d Communications Squadron (RAPCON),
who observed the incidents.
2. The objects were observed on both CPN-l8 (S-band) and FPN-l6
(X-band) GCA radars. When the objects were in position to be observed
by both radars, both radars reflected the targets at identical positions.
The CPN-l8 PRF was 1500 pps, and the FPN-16 PRF was l833 pps. Thus, it
seems unlikely that the objects were electronically generated false
targets. Maximum and minimum ranges s at which the targets appeared and
hilitio
and winds were generally out of the speeds (140-240
knots) and various headings (including alter headings) argue against their
being wind-borne. Atmospheric conditions during which targets were observed
varied from "very grim" weather with low overcast, to Temperature
inversion was suspected on one date but not inversion was suspected one date but not on others n others, Failure of known
aircraft in the area to make visual contact with targets does not completely
rule out existence of visible targets; the initial attempt at rule out existence of visible targets; the initial attempt observation
(10 April) by aircraft on final approach was in bad weather, and on l2 April
when an F-l02 was scrambled to attempt contact, the targets were not within
the precision the precision radar's scan and no altitude could be ascertained. All incidents
occurred at night.
