Automatic high-resolution adaptive beam-steering
First Claim
1. A method comprising:
- implementing, through electronic circuitry of a retro-directive antenna array comprising a plurality of antenna elements, a capability to ignore a jammer circuit by the retro-directive antenna array during presence of the jammer circuit, the electronic circuitry further comprising a plurality of mixers, each of which is configured to mix a Local Oscillator (LO) signal generated from a Voltage Controlled Oscillator (VCO) of a coupled VCO array comprising a plurality of VCOs with a signal received at an antenna element;
in the presence of the jammer circuit, moving, based on the implemented capability through the electronic circuitry, pointing of a receive beam of the retro-directive antenna array toward a remote transmitter and away from the jammer circuit; and
automatically fine pointing the receive beam toward the remote transmitter following the moving thereof such that the receive beam exactly points to, and tracks, the remote transmitter, the automatic fine pointing being effected through a secondary automatic servo loop implemented in the electronic circuitry associated with the retro-directive antenna array.

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.
