Abstract
A radar system includes a signal generator to generate a linear frequency modulated continuous wave signal as a base chirp, and one or more frequency shifters to generate respective one or more additional chirps from the base chirp. The radar system also includes two or more switches. One of the two or more switches obtains a portion of the base chirp as a base transmit signal, and remaining ones of the two or more switches respectively obtain a portion of each of the one or more additional chirps as one or more additional transmit signals for transmission by the radar system. At least a portion of the base transmit signal and the one or more additional transmit signals overlaps in time.
