1. A method for operating a retro-directive array, comprising:

  • receiving a first input signal at a first antenna in the retro-directive array, wherein the first input signal is substantially circularly polarized, the first input signal comprising two signal components associated with different orthogonal polarizations, and wherein the two signal components comprise a first quadrature signal;

    feeding the two signal components through a bi-directional quadrature gain (BQG) module, the BQG module to boost the first quadrature signal; and

    transmitting the boosted first quadrature signal through an associated second antenna in the retro-directive array.
