SUBJECT : System One Tests
REFACES : (a) Memorandum for froi
dated 16 March 1956. Subject: Evaluation s s
for System One
(b) S-Band and X-Band Antenna Patterns for System One
(Graphic Publication)
(c) SAPC 6135/A, Antenna Patterns
1. The bench tests requested in Reference (a) above have been com-
pleted and forwarded in References (b) and (c) above. The tests have been
satisfactorily completed.
2. The mock-up teats of Reference (a) have been discussed in detail
with - of Remo-Wooldridge and seem to be progressing satisfactorilyc
3. No planned System One flight tests results have come to
The System one results of the flight tests run to date are not
satisfactory to establish the capability of the System One. It is re-
quested that the flight tests of Reference (a) described in detail in
Paragraph 4 below be conducted as soon as practical.
4. An S-Band radar of known location, antenna pattern and power out-
put (its antenna pattern and power output as specified by its manufacturer
will fulfill this need) should be used as a target. The plane should fly
at normal operating altitude with S-Band antennas installed at 14 to the
horizon and after a normal pre-flight check. The path should start at a
point at least 100 miles from the target radar and the first leg will pass
directly over the target proceeding at least 100 miles beyond the target.
The plane should return on a path parallel to the above path at a distance
of 25 miles from the first path. Successive paths parallel to the first
path and at distances of 75, 125, 225, 275, 325 and 375 miles should be
covered (see attached sketch).
5. This test should be repeated with all factors identical except
(a) X-Band antennas to be used on System one and (b) an X-Band target radar.
