Patent abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a radar device may transmit a combined frequency modulated continuous wave (FMCW) radar signal, wherein the combined FMCW radar signal comprises: a first FMCW radar chirp generated based at least in part on a first set of transmission parameter values; and a second FMCW radar chirp generated based at least in part on a second set of transmission parameter values, wherein a transmission parameter value of the second set of transmission parameter values is different than a corresponding transmission parameter value of the first set of transmission parameter values. The radar device may detect a radar target based at least in part on a received signal corresponding to the combined FMCW radar signal and perform an action based at least in part on detecting the radar target. Numerous other aspects are provided.
