A non-transitory computer-readable storage device stores machine instructions. When executed by one or more processors, the machine instructions cause the one or more processors to determine a first inter-chirp time with respect to a first series of chirps; and determine a second inter-chirp time with respect to a second series of chirps, in which the second inter-chirp time is different than the first inter-chirp time and is based on the first inter-chirp time and a chirp dither value. In another implementation, an oscillator receives chirp configuration signals, which contain the inter-chirp times, and generate the first and second series of chirps with the first and second inter-chirp times, respectively. Transmitter circuitry, coupled to the oscillator, transmits each of the first and second series of chirps with the respective inter-chirp time.
