Abstract
In an example, a method is implemented in a radar system. The method may include transmitting, via transmission channels, a frame of chirps, the chirps transmitted having a programmed frequency offset that is a function of a transmission channel of the transmission channels that is transmitting the frame of chirps, receiving, via a receive channel, a frame of reflected chirps, the reflected chirps comprising the chirps reflected by an object within a field of view of the radar system, and determining a Doppler domain representation of the frame of reflected chirps having a Doppler domain spectrum that includes multiple spectrum bands, the object represented in at least a portion of the spectrum bands based on the reflected chirps, wherein the programmed frequency is configured to cause the Doppler domain spectrum to include a number of spectrum bands greater than the number of transmission channels.
