RADAR AND TELEMETRY OBSERVATIONS FOR TWO SATURN LAUNCH VEHICLES (AN ANALYSIS OF LINE OF SIGHT HF RADAR OBSERVATIONS FOR THE SA-5 AND SA-6 LAUNCHES AND SOME COMPARISONS WITH VHF TELEMETRY MEASUREMENTS)
TL;DRAbstract
Abstract : Recently released information concerning rocket-exhaust effects up in VHF telemetry transmissions for several launches of SATURN space vehicles has been compared with data obtained for line-of-sight HF radar observations of these launches. A correspondence of certain VHF attenuation events with HF radar echoes is noted, and some inferences connected with the behavior of r-f transmissions in the presence of flames for missiles using liquid and solid fuels, respectively, are presented. A correlation is made of the complex target echoes obtained on HF POLYSTATIC radars with performance of the S-I and S-IV stages of the SATURN vehicles. Variations of radar cross section for the HF targets are also presented.
