MEASUREMENTS OF INTERFERENCE LEVELS IN THE UHF BAND FROM AIRCRAFT ALTITUDES VOLUME I: DISCUSSION AND GRAPHICAL DATA.
Abstract
An investigation of electromagnetic interference at orbital altitudes was initiated to fill the need for environmental data essential to the design of reliable space communications systems. To help fill this need, Aerospace developed a swept superheterodyne radio-frequency interference receiver for flight on the Lincoln Laboratory LES-5 and LES-6 experimental communication satellites. The LES-6 receiver was adapted for use on an Air Force KC-135 aircraft. The receiver was designed to measure average power and peak power in the bands from 233 to 258 MHz and from 290 to 315 MHz. The aircraft was flown on a world-wide data collection mission during February and March 1967. A compilation of the data collected on this flight is presented in graphical form in this volume, and in tabular form in Volume II, the Appendix to this report. (Author)
