A F-10l FLIGHT TEST
Four flights were made during this reporting period. The
last of these flights produced the beet results from 40,000 feet
altitude to date, with the best resolution and strongest return.
Consistency of the mapping was notable, with almost no variation
over the full film on both near and far ranges. Targets identified
and resolved are the cities of Winchester, Va., Keyser, Romney and
Charles Town, W. Va., bridges and bridge construction, limits of
highway construction, fish hatcheries, an oil tank farm near
Woodbine, Md... and orchards at Romney and Charles Town.
Video level fluctuations in azimuth dimension are present on
all flights, which the instrumentation recordings '?ndicate.are
caused by antenna pitch variations. These pitch variations are
ed by loose DFUT control. Minimum antenna fluctuations of 0.5
peak to peak can be detected on the correlated film.
Typical dot dimensions on correlated film are 5 to 7 mils
o 25 feet) range dimension and 3 to 7 mils (15 to 35 feet)
azimuth dimension. Dots with 3 mil (15 feet) azimuth separation
are recorded,
ht 85 film exhibits very strongvideo with good contrast
and definition, since receiver attenuation could be reduced to
zero after AFT improvements provided stable antenna control with-
out added receiver attenuation.
Improvement in the correlation effort is noticeable, especially
In the far range sector. The far range picture had been consistantly
defocused with dots elongated in the range dimension. The defocusing

has been improved and,, on flight 85, the dots are comparable in
size and shape to those in the near range sector.
INSTRUMENTATION
The antenna accelerometer and antenna velocity channels of
Instrumentation were replaced with recordings of DFT Gate output
and DFT video signals to allow both ground and in-flight analysis
of D operation. These recordings revealed that a spectra of
energy existed at zero frequency as well as at the off-set frequency.
The zero doppler spectrum was caused by the large signal input
;ing as its own local oscillator. The radar operator's AFT meter
Indicated 220 cps when It should have been 8440 cps The frequency
indication was held low by the DC lobe around the Fib' line. D
operation was improved by reducing the signal input to the tracker
to a point that provided sufficient signal to noise to permit
tracking but reduce the zero doppler spectrum to a min
SYSTEM
No in-flight failures were encountered with the system. Two
receiver malfunctions occurred durlnt ground check operation.
Overall receiver noise was lowered by changing the IF amplifier
and adjusting TWT operating voltages.
Experimental model crossed-field amplifier transmitter number
001 was installed in place of the breadboard model. The new CFA
transmitter doubled peak and average transmitter power, giving
600 kw.
The Input circuit to the DFT mixer was modified to reduce the
amplitude of the applied video. Also, the OFT antenna servo loop
was modified to provide either a fast or slow integration time in
the tracker output amplifier. The long integration time will

eliminate fast antenna motions but still maintain response
long term drift angle changes.
AIR FORCE FLIGHT TEST
A schematic showing modification of the system interconnection
for the instrumentation changes has been completed. Modification
on frame #3 is half complete. Wiring of the ProQ ranmier and
instrumentation units is 60 per cent complete. These units will
be mounted off frame just forward of the Recorder. A modified
Power Meter HP431B is included to measure transmitted power.
An. interface electrical schematic was prepared to facilitate
communication with the customer and Minneapolis-Honeywell.
Shielding changes on the wiring for the Motion Compensation re-
quested by Minneapolis-Honeywell were included on this drawing.
No serious problem was encountered when the frame and truss
were fitted in the vehicle. Cable connections will be checked.
Quick disconnect waveguide flanges are being investigated
to facilitate noise figure measurements on the frame. Antenna
boresight instructions have been written and supplied to the
customer.
C ENVIRONMENTAL TEST
RECORDER #6 VIBRATION
Vibration in all axes was completed on the #6 recorder to
evaluate the efficiency of the following isolator configurations:
Lord JA8350 isolators mounted normally at 90 0 to the
roll and yaw axes and parallel to the pitch axis.
Lord JA8350 isolators mounted at 900 to the yaw axis
and 45 to the pitch and roll axes.

Lord J7148 isolators mounted normally.
Results of these tests showed less film degradation using the
Lord JA8350 isolators mounted normally. However, good isolation
was not obtained under all conditions with these isolators for
vibration above 350 cps in the pitch axis or above 450 cps in
the yaw axis.
Vibration was also performed in the yaw and pitch axes
using the JA 350 isolators and the J7148 isolators with recorder
covers removed to evaluate effects of cover vibration. Film
degradation was slightly less for normal mount of JA8350 isolators
with the recorder covers removed at vibration in the yaw axis
above 300 cps.
ANTENNA PRESSURE-TEMPERATURE
Pressurization leakage tests were performed on the antenna
at the design temperature, 500"F. The leakage rate at 4 9OF was
25 psi in 30 seconds compared to an allowable rate of 10 psi in
10 minutes. Investigation showed the fabric on one of the
radiating sticks had delaminated. Several other small leaks were
found at the joints between the sticks and manifolds, and at the
stick load screws. It is felt that the leaks at the manifold
joints may have occurred during vibration, but the pressure seal
on the laminate was maintained by the silicone rubber compound
until the temperature was increased.
T3 DESIGN EVALUATION
The report on correlator spatial filtering was edited and
released as STM-i)46. No other studies are underway.

odifications to Recorder 6 include t
1. Conversion to Eastman type 4401 thin based film.
This film is a Plus-X emulsion on a 2.5 mil milar base, which
increases film capacity from 250 to 500 foot capacity.
2. Sweep driver modification to reduce the tendency to
oscillate and reduce average transistor dissipation.
Increase in focus control potential to accommodate a
wider variation in the cathode ray tube parameters.
fit, Lowered impedance of focus modulation circuit to prevent
loading by the high voltage power supply.
5. Addition of two ten second delays in the turn-on procedure
the high voltage power supply in addition to the original 60
second warm-up period.
Recorder 1 was returned to Itek for adjustment,, clean-u
and repair of some minor items.
The 1 to 1 lens was returned to the manufacturer to aid in
the design of a field flattening attachment. It is intended that
this attachment be added to existing recorders to improve ed8e
resolution.
A vibration test was made of a new design on the M-3 mirror
casting. The conclusion reached is that the current design is
r,echanically adequate, though more complex to adjust during align-
ment.
Two more high voltage power supplies have been received after
modification by the supplier. The first of these supplies has
d all performance tests and after operating for 75 hours it
was installed in Recorder #6. Electrical acceptance tests were

started on the second H.V. supply.
General evaluation has started on the CRT sweeps. Results
the measurements on sweep timing, linearity and bowing thus
far indicate that none of these items prevent the unit from pro-
cing adequate maps but must be considered in future designs.
F WESTINGHOUSE CATHODE RAY TUBE POWER SUPPLY
The low voltage section of the power supply was checked out
using the breadboard high voltage section. After checking the
high voltage section in liquid freon, it was then potted in Sylga
#184.
Several problems have been encountered since potting. In-
stability in the 4 V was corrected by changing to a different
type of switching transistor. The input current was reduced
slightly by using speed-up capacitors in the base circuits of the
switching transistors.
All drawings of the interconnecting waveguide have been re-
leased for the fabrication of two sets. one set has been completed
and tested. Insertion loss measured 1.0 db and VSWR 1.1:1.
Aluminum waveguide of 6061-Al cannot be purchased in the T6
condition. Waveguide manufacturers purchase round tube stock of
6061-Al in O condition and rework it to rectangular shape. The
resultant waveguide is somewhere between the 0 and T3 conditions
but netspecified, guaranteed or uniform throughout the piece.
s having the capability to heat treat the waveguide indicated
that in addition to the problem of distortion the major problem
would be the shrinkage of the inside cross section dimensions.by
.007 to .012 inches during heat treat. Substitute materials are

not completely satisfactory at elevated temperatures. It was
decided to use the aluminum waveguide without heat treat for the
interconnecting waveguide.
A visit was made to the Dupont Corp. plant in Fairfield,
Connecticut, to discuss the problem of delamination of the fabric
seal. Much effort has been expended in an attempt to find a
solution. Dupont was pessimistic about solving this problem
with changes in manufacturing techniques and are now concentrating
their efforts on a new but similar resin. The use of this new
resin shows much promise in solving the delamination problem but
the resultant laminate must be tested fully for R F.. thermal and
bonding conditions before it could be considered as a replacement
for the ML Fabric. To this end a testing program is being pre-
pared to teat this and any other materials that may have been
recently developed.
H SYNCHRONIZER
The breadboard Frequency Generator was tested using the Field
Test Equipment and found to have a broadbanded control response and
an 18 cps deviation due to noise. The breadboard unit was improved
significantly by (a) obtaining the fixed frequency output from a
different point than the buffer stage that drives the offset mixer
and (b) adding a large integrating capacitor to narrow the control
bandwidth to 35 cps and also reduce the fm. of the VFO.
Drafting is complete on the diode switch and driver circuitry,
now called Frequency Generator output Gate. Fabrication will start
immediately. This gate provides 70 db of Isolation against leakage
of the Fixed Frequency output into the mixer during the inter-pulse
periods. The ON-time for the gate is set at 4 microseconds.

I MOTION COMPENSATION
All three of the motion compensation electronics with roll
table have been accepted from Honeywell. The first unit, however,
was returned for some rework, including an improvement of the
accelerometer and a change of wiring harness to make this identical
with the final two units.
During tests on the number two unit tied to a mechanically
accurate dummy antenna, several problems have developed. The
sliding bearing support which operates at high temperature without
lubrication chatters and binds. Even with lubrication it is not
ideal. This unsolved problem requires further investigation by
the actuator supplier, but changes in bearing friction will affect
servo operation, however. The frequency response of the antenna
yaw motion appears slow, but actual measurements are not complete.
Finally, the antenna displacement with respect to yaw voltage
command is non-linear. Linearity of the actuator and LiT pickoff
Is being checked with the actuator supplier. Gain of the actuator
position transducer is not determined by the supplier and may re-
quire matched transducers. These problems will have to be corrected
before delivery because of the. importance found in flight test of
the angle compensation.
L FIELD TEST EQUIPMENT
Full tests of the Field Test Equipment with the system have not
been possible because of the lack of some radar subassemblies. The
FTE was used for the series of tests on the breadboard, Frequency
Generator and for DFT tests on the F-101 equipment.
