Abstract
A procedure for control of a scanning antenna including: a central modulation-management unit (OBS) incorporating an external angular scanning and packet-synchronization bus (BRC), at least N modulation-control devices (MOD.sub.1, . . . MOD.sub.N), at least one beam-forming device (BFN), at least one network comprising M antenna elements (A.sub.1, . . . A.sub.M), the central management unit (OBS) incorporating N first terminals connected respectively to N second terminals of the beam-forming device (BFM) through the N modulation-control devices (MOD.sub.1, . . . MOD.sub.N), and the beam-forming device (BFN) incorporating, on the one hand, M third terminals connected respectively to the M antenna elements respectively (A.sub.1, . . . A.sub.N), and, on the other, a scanning and synchronization terminal connected to the external bus (BRC). Scanning is effected by aiming the beam in different preferred directions at the packet rate of a multiplex, so as to address the packets in the directions and to ensure continuity of synchronization.
