WebA fast-chirp signal generated by the PLL is distorted by its transient characteristic. The proposed method measures a frequency difference between the output and an ideal signal, and it modifies the division ratio of the PLL from the measurement result. WebA fast sawtooth chirp with high chirp slope needs to be synthesized to increase simultaneous velocity and range separation and improve target SNR in a low-cost CMOS technology.
