Abstract
Embodiments of the present disclosure disclose a phase-locked loop, a radar system and a method for randomizing initial phases of FMCW signals. The phase-locked loop includes a phase-locked loop circuit and a random control signal generator. In response to a clock signal indicating a respective target moment of one or more target moments, the random control signal generator inputs a random control signal to the phase-locked loop circuit, so that the accumulated value of the plurality of fractional frequency division values is converted into a random value, and that a plurality of phase differences respectively corresponding to the plurality of chirp signals form a non-arithmetic sequence.
