ABSTRACT:
A method and apparatus for deriving control signals for enabling an antenna to track a signal source and this antenna is operated to produce at least one beam having a maximum on the boresight axis and one beam having a minimum on the boresight axis, by deriving a sum signal associated to the beam having a maximum on the boresight axis and a difference signal associated to the beam having a minimum on the boresight axis, sequentially and cyclically varying the relative phase relationship between the difference and the sum signal among four different phase values, and combining the sum signal with the difference signal for producing signals constituting a source of the control signals for enabling the antenna to track the signal source.
