RECEPTION VIA THE SYNCOM II COMMUNICATION SATELLITE USING AN 8-FOOT PARABOLIC ANTENNA,
Abstract
Signals transmitted by the U.S. Army Satellite Communication Agency's Camp Roberts terminal via Earth satellite SYNCOM II were received at the Naval Research Laboratory using an eight-foot diameter parabolic antenna feeding into a parametric amplifier. The antenna system configuration provided performance capability equivalent to a 5.7-foot diameter parabolic antenna with 237K noise temperature. Phase lock frequency modulation detection circuitry was used for demodulation of the received signal. Voice reproduction was slightly distorted when the satellite was operating in the simplex mode with the Camp Roberts transmitter adjusted for 200 watts input to its 60-foot antenna (radiation efficiency - 55%). Received signal strength was found to be in agreement with predicted values. (Author)
