Dl FLIGHT TEST
S
Six radar missions to obtain data for altitude comparison
and two aircraft flights to evaluate repairs to a fire warning
system were flown in October. Specific information on the radar
flights is tabulated In Appendix A.
Flight 190 was flown at an altitude of .0,000 fee
recorder modified for the Field Flight Teat conditions and with
12 db r-f attenuation inserted to simulate the signa
conditions of flights at 80,000 feet. Flight 191 was flown
140, 000 feet using the normal P-101 recorder and r-f configuration
to provide a comparison. To verify the r-f attenuation, flight
192 was flown at 20,000 feet altitude with 12 db r-f attenuation,
simulating the signal-to-noise of a normal F-ldl 40,000 foot flight.
Other fly-bye were made on flight 192 with no r-f attenuation to
show the beat signal-to-noise at that altitude. on each of the
flights, the target area was the Delaware River from Wilmington,
Delaware, to Trenton, New Jersey. Repeatability of the course was
ood for the flights.

Less than optimum operation was obtained on flight 187
seeause an intermittent battery connection caused unreliable
quen.cy generator operation. A broken waveguide attenuator
between the buffer amplifier and transmitter sporadically re-
duced the r-f drive to the transmitter on both flights 187 and
at tutee causing weak video. Radio communication problems
ted aircraft altitude to a maximu of 24#000 feet on flight
A fire warning indication was observed on flight 187 similar
to that reported in. September on flight 186. Further tests indicated
the temperature sensors for the warning system were defective.
Since replac ent of the sensors, the problem has not recurred.
A mandatory 50 hour: inspection of the P-101 was started
following flight 192. A five day delay in flying is expected.
MODIFICATIONS AND GROG TESTS
The breadboard receiver was installed in the aircraft following
flight i86. A review of the history of video striping: such as
reported in September, indicated severe striping has never occurred
with the breadboard receiver. A comparison of breadboard and
production receivers is underway to determine the cause of striping.
In addition, stab reflector voltage has been instrumented.
Power ?upply
An overload occurred on the system 20 volt line during ground
warm-up prior to flight 187. Several loads in the 20 volt
distribution system were fused to isolate the source of the inter-
mittent overload if it should recur.
A -45A Camera
The camera was returned to the manufacturer again for correction
of the shutter malfunction. _),_

ANTENNA
All of the array sticks for Antenna 002 have been bonded
and given an 8 hour heat-pressure test at 550OF with a constant
30 prig internal air pressure. No failures occurred and no
bubbles appeared as a result of these tests.
Three modules have been assembled and electrically tested.
A comparison of these r-f patterns with earlier patterns indicated
no change in electrical properties. Soldering and then electro-
forming of the array sticks in the modules are the next procedures.
MODIFICATIONS

D CQRRGA'OR OPERATION
The triggering lamps for the data block transfer were relocated
and the sensitivity readjusted to provide better reliability in
the flash circuit. At present the far range is satisfactory.
Work will continue on the problem of transferring the data flash
on the near range.

E ORRELATOR MECHANICAL REVIEW
Both the technical memorandum and proposal on the White
Light Correlator Review are complete and will be released early
November.
Density of the output film varies across the range sweep
because of variations in antenna pattern, spectral content of the
rbon are., spectral sensitivity of the film spectral tranemi
of the rainbow filter, and the cosine fourth power effect of the
lenses in the optical system. Several correlations were made of
ht 137 using normal output slits, wider than normal slits,
and shaped slits to compensate for the uneven distribution. Results
of these tests showed little improvement in the non-uniformity of
density with shaped slits. Much of the non-uniformity is in the
ckground rather than actual target density and. may be due to
stray light. The extraneous reflected images and degradation,due
the wider alit was more objectionable than the original non-
uniformity. No further work is planned with shaped slits, The
Log-E- runic Dodging Printer can improve uniformity of 1 x 18
prints where required.
