Abstract
The present disclosure provides a radar front end chip that includes a plurality of encoders, each encoder of the plurality of encoders to receive a digitized radar signal and to encode the digitized radar signal with a phase code to generate one of a plurality of phase-coded digitized radar signals. The radar front end chip also includes a combiner to combine the plurality of phase-coded digitized radar signals into a digital radar data stream for transmission to a central radar processor.
