Abstract
Exemplary embodiments disclosed herein relate to a radar device. The radar device may transmit an RF oscillator signal to a radar channel and receive a respective first RF radar signal from the radar channel. The radar device may further generate a second RF radar signal. Frequency conversion circuits are also disclosed to down-convert the first RF radar signal and the second RF radar signal. An analog-to digital conversion unit may digitize the down-converted first RF radar signal and the down-converted second RF radar signal to generate a first digital signal and a second digital signal, respectively. A digital signal processing unit is disclosed to estimate a phase noise signal included in the second digital signal and to generate a cancellation signal based on the estimated phase noise signal. The cancellation signal is subtracted from the first digital radar signal to obtain a noise compensated digital radar signal.
