US Patent 11187783 Radar systems and methods for operating radar systems

Embodiments of a method and a device are disclosed. In an embodiment, a method for operating a radar system is disclosed. The method involves generating a chirp signal having a repeating pattern of chirps, each chirp in the repeating pattern of chirps having a base frequency and a chirp bandwidth, wherein the repeating pattern of chirps includes at least two chirps that differ from each other in at least one of base frequency and chirp bandwidth, transmitting a radar signal according to the chirp signal, receiving radio frequency energy that includes a reflected portion of the radar signal, and selecting for processing from the received radio frequency energy a signal that matches the repeating pattern of chirps of the chirp signal.
