Abstract
A method includes pointing a receive beam of a retro-directive antenna array attracted to a jammer circuit instead of a remote transmitter away from the jammer circuit toward the remote transmitter by a first angle based on coarse manual means therefor implemented in electronic circuitry associated with the retro-directive antenna array. The electronic circuitry includes a number of mixers, each of which is configured to mix a Local Oscillator (LO) signal generated from a Voltage Controlled Oscillator (VCO) with a signal received at an antenna element of the retro-directive antenna array. The method also includes automatically fine pointing the receive beam toward the remote transmitter by a second angle following the coarse pointing thereof by the first angle such that the receive beam exactly points to, and tracks, the remote transmitter. The automatic fine pointing is effected through a secondary automatic servo loop implemented in the electronic circuitry.
