Abstract

See full text

In some aspects, a radar device may receive a plurality of received signals comprising a plurality of reflected frequency modulated continuous wave radar signals and phase noise. The radar device may obtain a frequency-domain representation of the received signals comprising a plurality of frequency-domain spectrums. The radar device may determine a shaped noise component of the frequency-domain representation corresponding to a negative distance portion of the frequency-domain representation. The radar device may determine a shaped decision boundary for target detection based at least in part on the shaped noise component, wherein the shaped decision boundary corresponds to a positive distance portion of the frequency-domain representation. The radar device may detect a radar target based at least in part on the shaped decision boundary. The radar device may perform an action based at least in part on detecting the radar target. Numerous other aspects are described.
