This paper describes the ATHESA (Automatic THree-dimensional Electronic Scanned Array) technique for achieving very high antenna gain for deep-space communication systems. Phase coherence over a band of frequencies is established on reception automatically and continuously for either stationary or moving targets by phase-locking the signals from antenna elements separated by many wavelengths to a reference antenna element.
