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. TALE I P-l01 . PROGRAM SUGARY October 1965 Flights Scheduled Aircraft ar hts.

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. _),_ Approved For Release 2010/12/09: CIA-RDP67B00657R000200210007-6 SPECIAL 1 Approved For Release 2010/12/09: CIA-RDP67B00657R000200210007-6 IM1@UL11v V 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 The July 1965 progress report listed 15 minor modifications, of which 9 were complete at that time.

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.
