Various implementations described herein are directed to frequency correction for pulse compression radar. In one implementation, a method may include generating a first transmission signal using a pulse compression radar system based on an ideal waveform signal. The method may also include measuring a frequency of the first transmission signal at an output of a transmitter module. The method may further include comparing the measured frequency of the first transmission signal and a frequency of the ideal waveform signal. The method may additionally include generating pre-distortion coefficients based on the comparison, where the pre-distortion coefficients are configured to compensate for a difference between the measured frequency of the first transmission signal and the frequency of the ideal waveform signal. In addition, the method may include generating a compensated transmission signal using the pulse compression radar system based on the pre-distortion coefficients and the ideal waveform signal.
