Abstract : An experiment to prove the feasibility of arrays in satellite communications is now under way at Ohio State University. Four 30-foot reflectors have been instrumented for the University to make adaptively coherent the signals received by each dish from an Echo satellite. The satellite is illuminated by a remote transmitted signal. The effective gain of a 60-foot dish is obtained by the effects of slow irregularities in propagation and phase shifts, which are automatically compensated for in the signal-processing equipment. Acquisition, angle tracking, and several modes of cohering the parametric RF amplified signals are incorporated in this setup. (Author)
