There is little doubt that phased-array radars will continue to move toward the concept of digital phased-array radars, however, the optimal architecture is still debatable. The architecture discussed here, making use of JESD204B over optical, may enable entirely digital arrays for L-band, S-band, and C-band radars. This architecture reduces the total power and thermal requirements at each antenna element by eliminating the requirement for an FPGA to be near the data converters. Further reductions in optical transceiver size and power would make this architecture even more compelling.
