Abstract
Example embodiments described herein involve techniques for removing transmit phase noise. A system may cause a printed circuit board (PCB) to supply a signal enabling the transmission line to couple the signal to the radar unit and the delay line to couple the signal to the quadrature coupler. The radar unit may use the signal to transmit a radar signal on a radio channel having a centered radio frequency while the quadrature coupler uses the signal to produce an output from the quadrature coupler. The system may estimate phase noise relative to the radio channel having the centered RF based on the output from the quadrature coupler, receive, from the radar unit, a radar reflection corresponding to the radar signal, and determine information representative of one or more objects in an environment based on the radar reflection and the phase noise.
