Design

Existing Antenna Demonstrator at ASTRON 64 dipole antennas 16 electrical beamforming modules (1) perform TTD steering for 4 elements each 4 electrical beamforming modules (2) perform TTD steering for 4 columns each The four outputs are combined (S) without delay adjustment
Enhancement in this Project Last module (S) is replaced by a photonic module with 2 bit True Time Delay steering
