FREQUENCY-MODULATED CONTINUOUS WAVE GENERATOR AND FREQUENCY-MODULATED CONTINUOUS WAVE RADAR SYSTEM INCLUDING THE SAME

摘要

A frequency-modulated continuous wave generator according to the present invention includes a ramp signal generator configured to generate an analog ramp signal, a reference signal generator to generate a reference signal based on the analog ramp signal, a phase locked loop to output a control voltage based on the reference signal, and a voltage-controlled oscillator for generating a frequency-modulated continuous wave based on the control voltage. The ramp signal generator generates the analog ramp signal based on a feedback signal based on the frequency-modulated continuous wave. Accordingly, the present invention can generate the frequency-modulated continuous wave at high speed and improve the linearity of the frequency-modulated continuous wave.
