Practical Application Possibility of Holographic Antennas for Adaptive Signal Processing

In this paper, a perspective method of adaptive beamforming using a reconfigurable holographic feed-through antenna with external horn excitation is considered. This kind of system provides wavefield reception and emission as a result of waves passing through a diffraction plate with controlled amplitude or phase transmittance. The results of numerical modelling show the possibility of increasing the output signal-to-interference-plus-noise ratio and suppressing unwanted interference in received signals during plate reconfiguration based on the Cantoni orthogonal perturbation method.
