Abstract
A system and method of digital beamforming for a monobit phased array radar system includes providing a plurality of monobit analog signals received by at least one antenna to at least one field programmable gate array (FPGA). A plurality of monobit SerDes transceivers within the FPGA convert the plurality of monobit analog signals into a plurality of multibit digital signals, each of the multibit digital signals being modified according to a digital signal conditioning value to calibrate, phase align, and synchronize the digital signals. A digital beam is formed by coherently combining the plurality of digital signals within the FPGA.
