PHOTO INTELLIGENCE MEMORANDUM
ELECTRONIC INSTALLATION, FOOCHOW
This report was prepared in answer to a request for detailed photo
analysis of possible rhombic antenna installations located near Foochow,
China.
The antennas were located on the aerial photography of
The photos have a scale of 1:9450, and were taken with a 36" lens.
The location of the antennas was found to be 260 069 15" North
latitude, 1110 189 20" East longitude. Polyconic grid reference, Band
III N, Zone "D", 334553 Sheet 8833-II of AMS series L783, 1:5C,C00 was
used. This map sheet was also used in the determination of the angular
orientation of the antennas.
The orientation of the antennas was found to be _ This is the
orientation of both the large and the small arrays, using the long axes
as the references;,
The two antennae arrays are geometrically similar, as shown by the
arrangement of the poles. Each is symmetrical about both axes.
The heights of the poles could be determined only approximately,
although both parallax and shadow methods were attempted. Photographs
made from copy negatives were the only ones suitable for measurement

because the area on the original photos had been defaced. Because of the
poor resolution of the copy prints, precise heights could not be determined,
When other prints from the original negatives become available, better
height measurements will be made, if still desired.
The heights, distances between poles, and relative location of the poles
are shown on enclosures 1 and 2.
Aside from the poles, only one characteristic of the installation
was noted. It is a small building, enclosed by a compound-like fence,
and appears to be a part of the electronics-antenna complex.,
The heights of the poles are accurate only to about + 15?o The
distances shown are accurate to 51, and the orientatio 25X1D
