An L-band 4×4 dual-polarization array with full digital receiving beamforming using two synchronized radio frequency system-on-chip (RFSoC) is presented. The array has 32 dipoles, 16 for each polarization, connected to the 2×16 channels of the two RFSoCs. The constituting element for the array are two dipoles placed orthogonal to each other.
Details of the dipoles, the antenna array, the synchronized RFSoCs, and the calibration are provided. The digital beamformer is first compared with an analog beamformer for measured boresight patterns. Subsequently, digital beamsteering is demonstrated in elevation. The array provides the building block for larger arrays with application in synthetic aperture radar (SAR).
