Abstract: A method for a radar system includes transmitting, by a transmit channel of the radar system, a frame comprising first, second, and third chirps. Each chirp has a chirp start frequency, and the chirp start frequency of the transmitted chirps is dithered. The method also includes receiving, by a receive channel of the radar system, a frame of reflected chirps based on the transmitted frame, and generating a digital intermediate frequency (IF) signal.
