1. A method for determining the pointing direction of a phased-array transmit antenna relative to a remote station, where said phased-array antenna includes a beam- direction control arrangement, in a system in which a tone generator provides a test tone for near-field alignment of said beam-direction control arrangement of said transmit antenna, said method comprising the steps of:

  • generating said test tone for beam pointing determination, and applying said test tone to a port of said transmit antenna;

    controlling at least one of amplitude and phase of said beam-direction control arrangement of said transmit antenna for generating multiple beams;

    at a remote station in the case of a transmit antenna, determining, for each of said multiple beams, at least one of amplitude and phase of said tone;

    from said at least one of amplitude and phase of said tone, determining the pointing direction of said antenna relative to said remote station.
